[PATCH 2/2] kvm-unit-tests: configure changes for illumos.

[Dan Cross <cross@oxidecomputer.com>]

This change modifies the `configure` script to run under illumos
by not probing for, `getopt -T` (illumos `getopt` supports the
required functionality, but exits with a different return status
when invoked with `-T`).
