unix: add SchedSetAttr and SchedGetAttr for Linux

Add wrappers for sched_getattr(2) and sched_setattr(2), as well as
various SCHED_ values usable for these.

The kludge in linux/types.go is needed so we can include both
linux/sched/types.h (for struct sched_attr) and sched.h (for a few
defines from include/bits/cpu-set.h).

Unfortunately, they both define struct sched_param, thus the need to
mask one of the definitions.
