tests: Add a bunch of new tests to virsh-optparse

The new tests deal with numeric options of three kinds: regular,
scaled and timeouts. For each, both valid and invalid inputs
are provided, hopefully covering all cases: this should allow us
to avoid regressions when changing the relevant code in virsh.
