fix x86 conditional

The CpuInfoTest.SupportLevel testcase fails on s390x because wrong condition in
src/gromacs/hardware/tests/cpuinfo.cpp is used, (IMHO) on unknown architecture the GMX_TARGET_X86 symbol is defined to zero, but I expect it's fully undefined on known non-x86 arches.

Expected: (c.supportLevel()) >= (gmx::CpuInfo::SupportLevel::Features), actual: 4-byte object <00-00 00-01> vs 4-byte object <00-00 00-02>
No CPU features could be detected. 
GROMACS might still work, but it will likely hurt your performance.
Please mail gmx-developers so we can try to fix it.
