Remove X86_TSC dependency in net profile code

Alexey, time to remove the net profile stuff?

This removes one of the remaining users of CONFIG_X86_TSC

Replace it with a runtime test instead. In some configurations it will be still properly optimized because cpu_has_tsc will expand to a constant then.

This also makes it handle x86-64.

I did not actually compile test this because net profile is commented out since a long time and doesn't compile. An alternative if noone comes up to fix it would be just to remove it completely.

I decided to just kill net profile for now.

Thanks for bringing this to my attention Andi.
