scripts/oe-selftest: Allow to run tests on random/all MACHINEs

Add an option for random MACHINE into oe-selftest:
--machine [random/all]
1. random: will set a random MACHINE for each test
2. all: will run tests for all machines

Custom machine sets only weak default values (??=) for MACHINE in machine.inc.
This let test cases that require a specific MACHINE to be able to
override it, using (?= or =).

e.g.:
oe-selftest --run-tests signing --machine random -->
will run all tests switching MACHINE randomly for each test

oe-selftest --run-tests signing --machine all -->
for each machine will run all tests

oe-selftest --run-all-tests --machine random

Also update oeqa/selftest/base.py to accomodate this feature.

Fix for [YOCTO #5880].
