Rob Norris e4b8d6a56f linux/simd_x86: remove obsolete kernel feature gates 
Most of the X86_FEATURE_* defines we use were introduced in kernels much
older than those we support, so there's no need to check for them.

For the history, these are the ones being removed, and the kernel
versions/commits where they were introduced:
