chore(php-shim): drop the ob_start()/ob_get_clean() ports

Output buffering captures whatever the PHP interpreter would echo to
stdout. The shim routes no output through a buffer, so these functions
could never capture anything and stayed todo!(). Record the gap in
docs/known-incompatibilities.md instead.
