x86: Disable non-temporal memset on Skylake Server
The original commit enabling non-temporal memset on Skylake Server had
erroneous benchmarks (actually done on ICX).
Further benchmarks indicate non-temporal stores may in fact by a
regression on Skylake Server.
This commit may be over-cautious in some cases, but should avoid any
regressions for 2.40.
Tested using qemu on all x86_64 cpu arch supported by both qemu +
GLIBC.
