Properly set test tool dependencies for lit tests
Properly set test tool dependencies for lit tests

The syntax for `set_tests_properties` is `set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)`, so the DEPENDS properties has to be a list here.

This was missed in https://github.com/google/iree/pull/530 because I forgot to rerun the kokoro presubmit after the final commit. It turns out the original had a bug though and CMake was just treating LLVMFileCheck as a test property which it set to IreeFileCheck... That would've been a fun race condition to diagnose later.

Closes https://github.com/google/iree/pull/540
