Java: Remove some JNDI Injection sinks

[atorralba]

Removes JNDI Injection sinks that were causing false positives: LdapOperations.lookup methods receiving an AttributesMapper parameter don't actually call DirContext.lookup, but only DirContext.getAttributes. Also, adds tests and stubs for these cases.

Fixes #7699.

LGTM at a glance, but the test fails.

@aschackmull stubs needed fixing. All checks are now green.
