x86: Fix unchecked AVX512-VBMI2 usage in strrchr-evex-base.S
strrchr-evex-base used `vpcompress{b|d}` in the page cross logic but
was missing the CPU_FEATURE checks for VBMI2 in the
ifunc/ifunc-impl-list.
The fix is either to add those checks or change the logic to not use
`vpcompress{b|d}`. Choosing the latter here so that the strrchr-evex
implementation is usable on SKX.
New implementation is a bit slower, but this is in a cold path so its
probably okay.
