(misc/urjtag gettext-lib support)

This commit apparently fixes the PLIST problem on Linux.
Linux seems always gettext-lib available, while in
NetBSD (other *BSD ?) has it conditionally.
(As a side fix, add msgfmt to USE_TOOLS, thanks obache)

This commit adds gettext-lib support unconditionally.
Resulting some *.mo files are added to PLIST.
