format_commit_message(): simplify calls to logmsg_reencode()

All the other callers of logmsg_reencode() pass return value of
get_commit_output_encoding() or get_log_output_encoding().  Teach
the function to optionally take NULL as a synonym to "" aka "no
conversion requested" so that we can simplify the only remaining
calling site.
