lomiri.*: Make buildable while waiting for GLib fix

[OPNA2608]

Description of changes

#309952 broke lomiri.telephony-service and lomiri.lomiri-indicator-network. The fix is #314043 or a yet-to-be-released GLib bump, but I was told on our staging matrix channel that a staging iteration for 24.05 is not possible in time for the release. Try to disable/exclude the broken bits, see if we can get the DE mostly-functional again.

Still need to check how functional lomiri.lomiri-indicator-network still is. Too broken for the tests, but maybe regular desktop usage is okay.

Edit: Checked on spare hardware, seems to work fine.
