[PATCH 18/39] tests/functional: avoid accessing log_filename on earlier failures

[Alex Bennée]

From: Daniel P. Berrangé <berrange@redhat.com>

If a failure occurs early in the QemuBaseTest constructor, the
'log_filename' object atttribute may not exist yet. This happens
most notably if the QEMU_TEST_QEMU_BINARY is not set. We can't
initialize 'log_filename' earlier as we use the binary to identify
the architecture which is then used to build the path in which the
logs are stored.
