dvm: Bring back the ANDROID_DATA override

This got broken by the split-cache patch, and it's impacting the
CTS vm unit. Fixit.

Exclude sha1.c when building libdex for device

In bionic, there is already an optimized SHA-1 hash implementation,
and the file 'sha1.c' in libdex is almost identical.  It is only
necessary to build sha1.c for host version of libdex.

In addition, the SHA-1 hash implementation in bionic is slightly faster
than the one included in libdex.

Here is the reference SHA-1 benchmark on Nexus S:

[libdex]
Rounds: 100000, size: 6250K, time: 1.28s,  speed: 4.768 MB/s

[bionic]
Rounds: 100000, size: 6250K, time: 1.184s, speed: 5.156 MB/s

Fix a couple of minor publicly-reported GC bugs.

An assertion was incorrectly assigning rather than testing, and
there was the usual buggy attempt to recover from failure rather
than just aborting in the HeapSource.cpp dvmHeapSourceStartup.
(The Copying.cpp dvmHeapSourceStartup by contrast will just
segfault if an allocation fails, but that's fine too.)
