oeqa selftest wic.py: support UKIs via uki.bbclass

Use label to detect rootfs since UKI with kernel command
line is generated before rootfs is generated by wic.

Adapt wic tests to build and boot uki.bbclass generated
UKIs.

Keeping one UKI test in wic.py and rest of the UKI features
are tested with dedicated uki.py test. Add plain non-UKI
systemd-boot tests to wic suite for aarch64 and x86.
