Use a smaller hex digest in FIPS flag files when SHA-256 used.

1458b49a9e5 switched to using HMAC-SHA256 for FIPS integrity checks on
Android. However, the flag file was named after a full 64-byte hex
digest. The additional 32 bytes weren't uninitialised, but are still
superfluous. This change gets rid of them.
