LINGUAS should list language name on each line

intltool's Makefile.in.in looks up specified language code using:

http://bazaar.launchpad.net/~intltool/intltool/trunk/view/head:/Makefile.in.in#L59
> USER_LINGUAS=(snip)if test -n "`grep \^$$lang$$ $(srcdir)/LINGUAS 2>/dev/null`"(snip)

This code snippet means that LINGUAS is expected to list each
supported language name on each line one by one.

This patch simply fix current LINGUAS to follow such manner and
let translation files properly generated.

Merge changes from uim/1.8

Note for po/LINGUAS: in the past, we have a commit to
empty the file. However, this will make future merge harder.
So in this merge, we ignore #theslinux changes for the file.
This will require PKGBUILD to empty the file manually
Ignore uim/37c9bbf made for m17nlib

See also the pull request #25 on :uim project. The purpose of
the commit is to provide an option to switch on/off candidate
window when using :m17nlib. However, #uim-vi has its own patch
to provide an option for all generic IMs.
