drop GNU nproc(1) support in favor of getconf(1)

`getconf NPROCESSORS_ONLN' will succeed on GNU/Linux systems
anyways; and the non-underscore-prefixed invocation works fine
on all BSD flavors tested.

Thus the `nproc' and `gnproc' attempts will never be reached.
The only downside is we lose the ability to account for CPU
affinity, but that's probably not an issue since CPU affinity
(AFAIK) isn't a commonly-used feature.
