refactor(php-shim): make the fs mutators return Result

mkdir, rmdir, unlink and symlink each had a bool version and a _result
twin returning the io::Error, which left two names for one call. Keep
only the Result form and let the callers that want a boolean spell out
.is_ok(). Call sites that discard the outcome, as their PHP originals
do, are unchanged.
