3.16 backport: main/gptfdisk: fix bad uuid generation error

sgdisk 1.0.9 prints a scary warning on alpine 3.16:

Warning! Unable to generate a proper UUID! Creating an improper one as a last
resort! Windows 7 may crash if you save this partition table!

This has been tracked and resolved as https://bugs.gentoo.org/844073 and
is apparently due to an util-linux update, fixed in this patch:
https://sourceforge.net/p/gptfdisk/code/ci/6a8416cbd12d55f882bb751993b94f72d338d96f/

The other patch is unrelated but another fix we will probably need soon:
popt 1.19-rc1 has been released last week (June 7th, 2022), so we might
as well grab the patch now...

(cherry picked from commit 99d30f0b)
