[Cronet] Add run_findbugs=1 to gyp env
[Cronet] Add run_findbugs=1 to gyp env

It turns out that findbugs is run during compile instead of
as a separate step. Android CQ bots skip compile step for
Cronet CLs that only touch Cronet files, so there is a chance
we can break findbugs step even though we pass CQ.
