Max Makarov c99ed77d1a tests: pci: verify per-segment ACPI _UID in DSDT ...

Extend test_pci_multiple_segments_numa_node to assert that every
PNP0A08 host bridge in the guest DSDT exposes a unique _UID
matching its PCI segment id. Linux surfaces the evaluated _UID
value through /sys/bus/acpi/devices/PNP0A08:*/uid, so the check
is a single additional ssh command on top of the existing test
plumbing.

This test is used (rather than test_pci_multiple_segments) so
that the assertion runs on both x86_64 and aarch64: the numa_node
variant boots through edk2 firmware on aarch64, making ACPI (and
PNP0A08 host bridges) available, whereas the non-firmware variant
uses FDT on aarch64 and exposes no PNP0A08 nodes.

Without a per-segment _UID, two PNP0A08 nodes share _UID=0 which
violates ACPI 6.5 section 6.1.12 and triggers BSOD 0xA5 on
Windows guests. This assertion would catch any future regression
of that kind.
