lib: s390: fix guest length in uv_create_guest()

The current code creates secure guests with significantly more memory
than expected, but since none of that memory is ever touched,
everything still works.

Fix the issue by specifying the actual guest length.

The MSL does not contain the length of the guest, but the address of
the last 1M block of guest memory. In order to get the length, MSO
needs to be subtracted, and 1M needs to be added.

lib: s390x: uv: Add pv host requirement check function

When running PV guests some of the UV memory needs to be allocated
with > 31 bit addresses which means tests with PV guests will always
need a lot more memory than other tests.
Additionally facilities nr 158 and sclp.sief2 need to be available.

Let's add a function that checks for these requirements and prints a
helpful skip message.

Every PV guest needs its own ASCE so let's copy the topmost table
designated by CR1 to create a new ASCE for the PV guest. Before and
after SIE we now need to switch ASCEs to and from the PV guest / test
ASCE. The SIE assembly function does that automatically.
