main/postmarketos-base-ui-gnome: fix polkit conflict, pt. 2 (MR 5886)

Move the polkit-elogind into depends= instead of pmb_recommends=, so
packages depending on postmarketos-base-ui-gnome can build successfully
again. The previous fix only helped for "pmbootstrap install", this fix
will help for both cases.

Without this, e.g. postmarketos-base-ui-gnome-mobile fails to build:
https://builds.sr.ht/~postmarketos/job/1384469
[ci:skip-build]: already built successfully in CI
