main/postmarketos-ui-plasma-mobile: disable x86 (MR 1508)

postmarketos-ui-plasma-mobile has plasma-camera in _pmb_recommends.
plasma-camera does not build for x86, because mpg123-libs-1.26.3-r0 is
still broken in Alpine edge repos (aports#11807).

Disable postmarketos-ui-plasma-mobile for x86 again, so the CI check
test_aports_ui doesn't fail anymore with:
postmarketos-ui-plasma-mobile/APKBUILD: package 'plasma-camera' from _pmb_recommends not found for arch 'x86'

[ci:skip-vercheck]: only modifying arches
[ci:skip-build]: unfortunately, postmarketos-ui-plasma-mobile fails to
build for x86_64 too due to broken libdv in Alpine (aports#11892).

I'll create MRs to Alpine to fix the broken depends, so we should be
able to enable it again soon.
