We already avoid system framework paths while looking for LDAP headers
to avoid issues.
Do the same while looking for LDAP libraries. This makes sure to find
the regular ldap library (`libldap.tbd`) instead of picking up
`ldap.framework` and let that seep into `libcurl.pc` with a full path.
This makes LDAP detection work on Apple as before introducing FindLDAP.
Follow-up to 49f2a23d50 #15273
Closes #15895
