    tests: Use tmp file to dump test results
    
    When running installed tests, the working directory for Cogl tests is
    in /usr/libexec/installed-tests, which isn't writable by normal users.
    
    To avoid the adding stray hidden files to the current directory,
    adapt the runner script to fallback to $(mktemp) - which is
    available on all platform we care about - and avoid adding
    hidden files everywhere.
    
    (Originally commit 05ab8eebe8f37d437fb915a2dafe0c0bb68e3950 in mutter's
    fork of cogl.)
