Fix cortex-a53 inclusion of files.

I accidentally broken the cortex-a53 because it directly includes files
from cortex-a15. Rather than revert that part, just copy over the files
that are needed directly so we don't run into this in the future.

Test: Built the aosp_angler-userdebug target using cortex-a53 as the
Test: arm target. Then built the bionic unit tests and ran them on
Test: an angler.

Make prctl test check maps.

It turns out that sometimes this kernel bug can be present but not
trigger a crash. Modify the test to check for overlapping maps instead.

Bug: 32640542

Test: Verified that this fails on a device without the kernel patch
Test: (both bionic-unit-tests32 and CtsBionicTestCases32). Verified

Eliminate deadlock in forked child due to delayed resetting mutex lock

For some program implementation, the pattern like below, calling
pthread_atfork to register atfork interfaces.

    pthread_atfork(&atfork_prepare, &atfork_parent, &atfork_child);

When the program is expected to reopen the shared library's handle
inherited from parent in child process. Maybe, dlclose is called in
atfork_child to release the shared library handle before reopen it.
Then, dlclose will indrectly call _cxa_finalize and finaly call
__unregister_atfork when dso is not NULL.

    atfork_child() -> dlclose() -> __on_dlclose()
     -> __cxa_finalize() -> __unregister_atfork(dso)

In __unregister_atfork, firstly, it try to hold the g_atfork_list_mutex
lock to operate the g_atfork_list. Due to the registered atfork_child is
executed before resetting g_atfork_list_mutex lock in child, the child
process will be blocked here because of deadlock.

Test: bionic-unit-tests32 --gtest_filter=pthread.pthread_atfork_child_with_dlclose
without the fixing, the test will be timeout.
