[cmake] Remove unused ${LLDB_PLUGINS} dependency from our Objective-C++ CMake config

[teemperor]

Summary

LLDB_PLUGINS doesn't exist as a variable, so this line doesn't add any dependencies and is
just confusing. It seems this slipped in from the gdb-remote CMake I was using as a CMake template.

The gdb-remote CMake itself is using a local LLDB_PLUGINS variable, so that code is fine.
