compat: add canonicalize_file_name
the POSIX 2008 behaviour of realpath is not available everywhere so we provide a simple wrapper function. We use (and provide) the gnu extension canonicalize_file_name to make it cleaner to test for the feature we need; otherwise we have to rely on realpath segfaulting if the second argument is null.
