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.
