Another attempt to fix "could not find clang-check" lit warning in analyzer-less builds

r359717 added clang-check as a dep of check-clang unconditionally
because I had missed lit.local.cfg in test/Tooling.

Instead, only add clang-check to the tools if the analyzer is enabled,
since the build target only exists then, and since all tests using
clang-check are skipped when the analyzer is disabled.
