make_ext4fs: fix block allocation to be best-fit

The block allocation algorithm was failing to allocate parts of large
files out of partially filled block groups.  Update the allocation
algorithm to be a simpler best fit loop - if the remaining length to
allocate is larger than any single contiguous region, allocate the
largest single contiguous region and continue allocating, otherwise
allocate the smallest contiguous that can hold the length.

Add the -u option to support running on USER builds

Because USER builds do not have root access, the new -u
option modifies the script to create a 512 Mbyte file
in /data/local/tmp/testfile, and use that for testing.
Read tests are disabled (because the inability to drop
the caches makes them pointless), and the write tests
now go through the filesystem layer, so it is not fair
to compare these results to a non-userbuild run.  However,
this test can help with before/after tests to see if
a change has improved the I/O performance of the system.
