Skip tests if ldap_set_rebind_proc() is not available

[cmb69]

This is already done by ldap_set_rebind_proc_error.phpt, but not by the other two affected tests.

---

Note that while ldap_set_rebind_proc_error.phpt has this check right, it, the check for the server being available is borked, because it mixes URI and hostname.

php-src/ext/ldap/tests/connect.inc

Line 10 in 228c271

$uri = getenv("LDAP_TEST_URI") ?: 'ldap://localhost:389';

but why not PHP-8.2 ?

For no particular reason. Applied to PHP-8.2 and merged up.
