loader: stop relying on AT_BASE

android loader should not rely on the fact
that AT_BASE is set because kernel currently
does not set it when linker is run standalone
(The linker does not have PT_INTERP set)

This commit replaces AT_BASE with calculated value.

linker: add more directories to default lib paths

Due to b/33681361, libraries are now installed to different paths than
before. In order for linker to load libraries from the new paths, the
default lib paths are updated.

However, this patch is temporary; different paths must be used depending
on whether the process is executing vendor executable or framework
executable. For example, vendor executable should not be able to access
/system/lib/, which is for framework-internal libs. Similarly,
framework executables should not be able to access /vendor/lib.

We have several solutions (linker namespace and DT_RUNPATH) to support
the scenario, but haven't concluded which is better. Furthermore, if we
restrict the search path right now, it will break many parts of Android
that are not yet prepared for the restriction. So, until then, we
temporarily use the single search path for both framework/vendor
executables.

Update timezone data to 2017a

IANA changes:

   Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
   discontinues DST.

   Changes to future time stamps

     Mongolia no longer observes DST.  (Thanks to Ganbold Tsagaankhuu.)

     Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
     Its clocks diverge from America/Santiago starting 2017-05-13 at
     23:00, hiving off a new zone America/Punta_Arenas.  Although the
     Chilean government says this change expires in May 2019, for now
     assume it's permanent.  (Thanks to Juan Correa and Deborah
     Goldsmith.)  This also affects Antarctica/Palmer.

   Changes to past time stamps

     Fix many entries for historical time stamps for Europe/Madrid
     before 1979, to agree with tables compiled by Pere Planesas of the
     National Astronomical Observatory of Spain.  As a side effect,
     this changes some time stamps for Africa/Ceuta before 1929, which
     are probably guesswork anyway.  (Thanks to Steve Allen and
     Pierpaolo Bernardi for the heads-ups, and to Michael Deckers for
     correcting the 1901 transition.)

     Ecuador observed DST from 1992-11-28 to 1993-02-05.
     (Thanks to Alois Treindl.)

     Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
     (Thanks to Stepan Golosunov.)

   Changes to past and future time zone abbreviations

     Switch to numeric time zone abbreviations for South America, as
     part of the ongoing project of removing invented abbreviations.
