recovery: Drop the dependency on libcrypto_utils.so and libsparse.so.

They're only needed in past when we statically linked libs that had
dependencies on them. Dropping them doesn't affect the recovery image
size, as there're still other users of the libs. But this would avoid
the false dependencies on them.

Test: `mmma -j bootable/recovery`
