native go fuzzing: Restrict fuzzer lookup to *.go

[pjbgf]

Projects containing words starting with Fuzz in non-go files break compile_native_go_fuzzer with the error:

sed: -e expression #1, char 15: unknown option to 's'

LGTM

The infra tests failure seems to be orthogonal to the changes in this PR. I will rebase with the latest to kick-off a retry.

Looks still failing?

[pjbgf]

Yes, I tested the same version of the code base without my changes and the error was still there.

I wonder whether something broke that test since the last time it passed. The last successful run was triggered by the sort_index branch being merged: https://github.com/google/oss-fuzz/actions/workflows/infra_tests.yml.

Comparing the changes since last pass I could not find anything I could point out as the issue. But I am not very familiar with the code base, so any help would be greatly appreciated.

The failure does not seem related to your change, it is from our infra:
https://github.com/google/oss-fuzz/runs/7834055737?check_suite_focus=true#step:9:873

Let's see how trial_build goes.

Merging this as the trial_build failure is irrelevant.
