configure.in,lib/Makefile.am,lib/po-to-msg.pl: Fix .msg file
generation to work when srcdir != builddir. Drop the "dontextract"
mechanism which automatically generates headers to allows building a
version with translations for the messages for errors in loading the
messages file, as it doesn't seem worth the effort to get it working
again. It's easy to write such a header by hand if you really want
to do this.
