fix: build_gen use lro gapic as lro dep

[noahdietz]

Go back to using the local (to googleapis) //google/longrunning:longrunning_go_gapic target as the LRO gapic dep for other go_gapic_library targets. googleapis/gapic-generator-go#405 fixes the shading issue that required the remote dep @com_google_cloud_go//longrunning/autogen:go_default_library be provided.

LGTM,
Does it mean we technically need to regenerate all BUILD.bazel files?

I have a CL ready that updates all of the targets.
