pretty: add support for "valueonly" option in %(trailers)

Browse Source 
With the new "key=" option to %(trailers) it often makes little sense to
show the key, as it by definition already is knows which trailer is
printed there. This new "valueonly" option makes it omit the key when
printing trailers.

E.g.:
 $ git show -s --pretty='%s%n%(trailers:key=Signed-off-by,valueonly)' aaaa88182
will show:
