linux: Remove /proc/cpuinfo fallback on alpha and sparc

There is no much gain in fallback to cpuinfo if sysfs is no present,
usually on restricted environment neither will be present.  It also
simplifies the code and make all architecture use the sched_getaffinity
as the sysfs fallback.

Checked on sparc64-linux-gnu.
