[PATCH] xfstests-bld: Simplify determination of number of CPUs in build-all

[Sedat Dilek <sedat.dilek@xxxxxxxxx>]

Use 'getconf _NPROCESSORS_ONLN' to determine the total number
of available ("online") CPUs.

I have seen this 1st in some build-scripts of Grml project and
had some discussions with Thorsten Glaser on this topic.
