Fix typo in LDAP stub

[haszi]

I think using ORALDAP instead of HAVE_ORALDAP which is used everywhere else was a typo. If it wasn't, feel free to close this PR.

Yup, I think so too...

I probably should have opened an issue first but re-opening this to see whether this was indeed a typo or not.

Thanks for reporting this and opening a PR. This probably could even go into PHP-8.2 branch but it would introduce 3 new PHP constants in case of Oracle client's ldap implementation (this is different than the OpenLDAP):

• GSLC_SSL_NO_AUTH
• GSLC_SSL_ONEWAY_AUTH
• GSLC_SSL_TWOWAY_AUTH

Because this ORALDAP symbol has been there since the beginning of the implementation in php-src. Therefore the master branch is fine to fix this and have these new symbols there.

Interesting that no one has noticed this, I guess these constants were never used.
