The php cli sanity check should report why it failed

[mainframe98]

When the sanity check for php cli fails, it just prints cli failed sanity check without the reason why the sanity check fails. It suggests to try again with --debug for extra details, but that doesn't change the error message.

In my particular case, the failure is because php cannot load a library, which causes it to output warnings alongside the expected hello. That extra output should be printed to the console to aid with debugging, similar to the check done for the micro build target.
