Since commit c055e3eae0f1 ("crypto: xor - use ktime for template
benchmarking") the benchmarking works just fine even for TT_MODE_INFCPU,
so drop the workarounds. Note that for CPUs supporting AVX2, which
includes almost everything built in the last 10 years, the AVX2
implementation is forced anyway.
CONFIG_X86_32 is always correctly set for UM in arch/x86/um/Kconfig,
so don't override it either.
