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
(manually cherry-picked commit 55ac5b0a908b85c050f34dc603f62dd4b1fc4e9f)
