selftests/x86/entry_from_vm86: Add test cases for POPF
POPF is currently broken -- add tests to catch the error. This
results in:
[RUN] POPF with VIP set and IF clear from vm86 mode
[INFO] Exited vm86 mode due to STI
[FAIL] Incorrect return reason (started at eip = 0xd, ended at eip = 0xf)
because POPF currently fails to check IF before reporting a pending
interrupt.
This patch also makes the FAIL message a bit more informative.
