Subject: test/ruby/test_process.rb: GID.from_name may raise Errno:ESRCH

getgrnam(3) says:
```
ERRORS
       0 or ENOENT or ESRCH or EBADF or EPERM or ...
              The given name or gid was not found.
```

Process::GID.from_name raises an ArgumentError for 0, but Errno::ESRCH
for ESRCH.  Actually, WSL 2 raises Errno::ESRCH.  This change accepts
all exceptions above.
