Use exclude or another method to cause cmd-repo-mod.bash to ignore certain directories

[spkane]

cmd-repo-mod.bash will find all directories with a Go module except those that match */vendor/*; however, there are times when I need it to ignore more patterns then this.

For the moment, I have forked the repo and just hard-coded a workaround, but it would be really useful if that script would respect exclude or have some other mechanic to pass in a list of patterns.
