Use FIPS-compatible SHA256 for comparing files

On systems in FIPS mode MD5 is not available, just use SHA256.

NOTE: I'm not sure if this changes makes ironic fully operational
      in FIPS mode, merely fixing an immediate issue.

Use SHA256 for comparing file contents instead of MD5. This improves FIPS
compatibility.
