check_procs: Use the range/threshold support functions from libnagiosplug.

This adds support for @<range> and makes stuff a bit simpler by removing code
duplications.

Note: Previously, the compatibility code for 'check_procs <warn> <max>'
accepted something like 'check_procs -w 10:-1 -c 10:-1 20 50' as well
(treating it as if '-w 10:20 -c 10:50' was specified). This is no longer the
case ... additional arguments are only used as warn/crit thresholds in case
-w/-c is not specified at all.
