Use released pot file and stop rebuilding it on-the-fly
Use released pot file and stop rebuilding it on-the-fly

For reproducible builds, the pot file should not be updated for no good
reason and this happens all the time during development. There is also
no point in recompiling gmo files all the time after unrelated source
changes.

Instead, the update_pot target will rebuild po/icewm.pot when requested,
and translation files will be only built when the pot file exists.
