    tests: Isolate directories in gdbus-peer test
    
    So that the tests all end up using separate `.dbus-keyring` directories,
    and hence not racing to create and acquire lock files, use
    `G_TEST_OPTION_ISOLATE_DIRS` to ensure they all run in separate
    disposable directories.
    
    This has the added benefit of meaning they don’t touch the developer’s
    actual `$HOME` directory.
    
    This reduces the false-failure rate of `gdbus-peer` by a factor of 9 for
    me on my local machine.
