Remove PHP_SETUP_OPENSSL inactive 3rd argument (php#14323)

If OpenSSL is not found, the PKG_CHECK_MODULES errors out already. To
not introduce too big of a BC break with possible PECL extensions using
this macro, it is perhaps simpler to remove this non-working argument.
Redundant macro arguments are ignored by Autoconf anyway.
