handling newer msgfmt files (digikam, ktorrent3 etc)

[David Brownlee <abs%NetBSD.org@localhost>]

        ktorrent has a nasty little awk file to mangle .po files
        so they can be handled by the msgfmt 0.14.4 in NetBSD 4.0
        (attached for reference)

        Should it be pulled into mk/tools/msgfmt.sh?
