[PATCH v2 1/4] test: Don't skip tests if nfit modules are missing

[Santosh Sivaraj <santosh@fossix.org>]

For NFIT to be available ACPI is a must, so don't fail when nfit modules
are missing on a platform that doesn't support ACPI.

Changelog:
v2:
  * Patch 2: Fix a bug, I skip erroring out if PAPR family, but condition had INTEL family instead.
    That change was there to test the same code on x86, but accidently committed. Now have
    a environment variable to force test PAPR family on x86.

  * Patch 4: Remove stray code, artifact of refactoring in patch 1.
