Subject: [PATCH] virt UEFI fix backport (#312)

* virt: serial and console fixes

While reworking the tests, I figured out the serial and console update
one wasn't quite right and it has shown errors in the code too.

* Convert the virt test_update() test to pytest and split it

Convert the huge test_update() function to pytest. While at it, also
split it into smaller more manageable test functions.

* virt: fix update of efi=True

Libvirt uses efi=True as a flag to look for the proper UEFI loader and
nvram template. This means that on a subsenquent state apply efi=True
will trigger a definition update even if not needed.

In case efi=True is provided, don't udpate if loader and nvram values
are already set.

* virt: remove useless try/except

* Reverse all asserts in code introduced by PR#59189

Asserts need to have the actual value on the left hand side and the
expected one on the right hand side. Reverting these in the newly
converted code.

In order to ease backporting to openSUSE package, this commit will remain
separate.
