images/regfile.proto: adds additional fields to RegFileEntry

Browse source 
This adds build-id, checksum, checksum-config and checksum-parameter fields
to RegFileEntry to store metadata used for file verification.

build_id: Holds the build-id if it could be obtained

checksum: Holds the checksum if it could be obtained

checksum_config: Holds the configuration of bytes for which checksum has
been calculated (The entire file, first N bytes or every Nth byte)

checksum_parameter: Specifies the value of 'N', if required, for the
configuration of bytes
