Replace gettext.ldgettext with gettext.dgettext in Anaconda exception handler
since ldgettext was removed in Python 3.11. Without this fix, the exception
handler crashes with AttributeError when trying to display errors, resulting
in raw tracebacks instead of the meh dialog in both GUI and TUI modes.
Also clean up stale __pycache__ directories from previous extractions and
add validation to ensure ldgettext is completely removed.
