Fix regression where custom ErrorProne checks were not run

Fix bug where all custom ErrorProne checks were not running.
Introduced by:
https://chromium-review.googlesource.com/c/chromium/src/+/1252006/

Changing the jar wildcard from * to *.class excluded metadata
files generated by Autoservice which were needed to load
the custom ErrorProne checks.

This CL reverts that pattern change.
