util/xmlpool: Update for meson generation

Meson won't put the .gmo files in the layout that python's
gettext.translation() expects, it puts them in the build directory in a
flat layout. This modifies android and autotools to do the same (scons
doesn't work with translations at all)

v3: - Squash 4 patches into this patch
