USES+= gettext-tools on 5 ports

These ports require msgfmt.  FreeBSD doesn't fail to build these ports
because a default option on gvfs brings in this tool.  The same gvfs
option is off by default on DragonFly and thus the missing dependencies
were unmasked.  Explicitly add gettext-tools to get msgfmt.
