[GTK] Fix and improve dist hooks for translations
https://bugs.webkit.org/show_bug.cgi?id=112519

Reviewed by Carlos Garcia Campos.

Source/WebCore:

* GNUmakefile.am: move translation-related rules and lists to the po directory's
GNUmakefile.am.

Source/WebCore/platform/gtk/po:

* GNUmakefile.am: move dist-related rules here; also move translation-related files
to this file's EXTRA_DIST, making sure to only list the files we actually want
shipped, so junk such as .orig, .rej and backup files do not end up in the tarball.

Source/WebKit/gtk:

* GNUmakefile.am: removed left-over translation files from EXTRA_DIST
