Konstantin Belousov 84eaf2ccc6 x86: stop punishing VMs with low priority for TSC timecounter
I suspect that virtualization techniques improved from the time when we
have to effectively disable TSC use in VM.  For instance, it was reported
(complained) in https://github.com/JuliaLang/julia/issues/38877 that
FreeBSD is groundlessly slow on AWS with some loads.

Remove the check and start watching for complaints.
