updater: send hash file contents

Send the hash file contents to the firmware image or tarball can be
verified, for whatever verification process is used by a platform.

Tested: Verified md5sum of /tmp/bmc.sig matches the signature file's
hash on the host.  Sent the contents over P2A.  The implementation uses
the same data pathway for the firmware image and the signature file.
