[PATCH v11 11/12] iotests: fix loading of common.config from tests/ subdir

[Daniel P . Berrangé]

common.rc assumes it is being sourced from the same directory and
so also tries to source common.config from the current working
directory. With the ability to now have named tests in the tests/
subdir we need to check two locations for common.config.
