Print SHA1 of the patch if bsdiff fails with data error

Browse Source 
This will help us to identify the patch corruption.

Meanwhile fix a wrong size parameter passed to bspatch.
(patch->data.size() into patch->data.size() - patch_offset).

Also remove the only usage of "ApplyBSDiffPatchMem()" and inline its
Sink function for simplicity.

Bug: 37855643
Test: Prints SHA1 for corrupted patch in imgdiff_test.
