features check, enforce, hv_relaxed and hv_vapic are treated as boolean set to 'on'
when passed from command line, so it's not neccessary to handle each of them
separetly. Collapse them to one catch-all branch which will treat
any feature in format 'foo' as boolean set to 'on'.

PS:
Any unknown feature will be rejected by CPU property setter so there is no
need to check for unknown feature in cpu_x86_parse_featurestr(), therefore
it's replaced by above mentioned catch-all handler.

v2:
  * use feat2prop() to perform name convertion for hv_vapic and hv_relaxed

This one I had already fixed, thanks for pointing out the other one.
