I saw similar issue as #6831. Is GID also not unique on OSX?

[ 69/110] TestEtc#test_getgrgid = 0.02 s

1) Failure:
test_getgrgid(TestEtc) [/Users/hiroshi/src/ruby/test/etc/test_etc.rb:84]:
<#> expected but was

I confirmed this patch fixes the failure.

No unixen systems guarantees that GID is unique.
Please commit it.
