[CMake] In standalone builds, LLVM_BINARY_DIR should point to LLVM's binary directory

[sgraenitz]

Summary

In standalone builds LLVM_BINARY_DIR was equal to LLDB_BINARY_DIR so far. This is counterintuitive and invalidated the values of LLDB_DEFAULT_TEST_DSYMUTIL/FILECHECK/COMPILER etc.

[sgraenitz]

Use LLVM_BINARY_DIR when checking for existance of libc++ include directory

[labath]

Makes sense to me.

typo (but BINRAY sounds cool, we should make that mean something :P).
