    cogl/tests: Use temp log file when .log isn't writable
    
    When running installed tests, the working directory for Cogl
    tests is /usr/libexec/installed-tests/mutter-cogl-4/conform,
    which isn't writable by normal users.
    
    To avoid the need of running those tests as root, adapt the
    runner script to fallback to $(mktemp) - which is available
    on all platform we care about - and avoid trying to write to
    unwritable files.
