  Changed paths:
    M llvm/test/tools/UpdateTestChecks/lit.local.cfg
    M llvm/test/tools/UpdateTestChecks/update_cc_test_checks/mangled_names.test

  Log Message:
  -----------
  Only run mangled_names.test if python3 is available.

The %update_cc_test_checks substitution only gets added if python3
is on path, so the test fails if it isn't. Don't run the test
when it would fail.

Also include the '%' in the arg to add_update_script_substition(),
to help greppability.
