vfio: selftests: Allow builds when ARCH=x86

Browse Source 
Allow builds when ARCH=x86 since the top-level Makefile can set ARCH=x86
even for 64-bit x86 builds.

Note that ARCH=x86 could also indicate a native build on a 32-bit x86
host. However, it doesn't seem like anyone is building selftests
natively on 32-bit x86 hosts these days since KVM selftests allow
ARCH=x86 and fail to compile on 32-bit x86.

If someone reports an issue on 32-bit native builds we can harden the
KVM and VFIO selftests to explicitly check 64-bit (see the discussion in
the Closes link below).
