Fix a small leak and re-utf8 of grep cmd / extra options in Messages

ixed a small memory leak (argv_prefix) introduced with the spawning
change. Simplified the utf8_dir handling, there's no reason to re-
convert it to utf-8. Restored the original grep command display in
Messages (as entered in Tools vs. found by g_find_program_in_path),
but fixed the re-utf8-izing of the command and extra options.
Grouped in one commit, since these changes affect the same lines,
and are actually small.
