[Libguestfs] [PATCH 3/3] builder: enable batch mode when validating non-verbose (RHBZ#1180170)

[Pino Toscano]

When running gpg to validate a signature, use also --batch in
non-verbose mode to avoid the extra "Good signature" messages that are
printed by gpg2 even in quiet mode.
We are parsing the status output anyway to check the validation result,
so this should be harmless (and the full gpg output is printed in
verbose mode anyway).
