generatepot-rst.sh: Drop UUID filtering

tools/generatepot-rst.sh has an awk filter to drop UUID from POT files,
but it is unnecessary now. It was introduced to strip UUID information
which was added by default in Sphinx <1.3 [1]. Sphinx >=1.3 does not
output UUID information by default [2], so is is no longer needed.

In addition, (g)awk 5.0 or later (adopted in Ubuntu 20.04 or later)
complains the current awk regexp. I think it is the time to drop it
rather than fixing the regexp.
