Using portage to bootstrap gentoo install can lead to the following
warning when ROOT is empty:

>> Running pre-merge checks for acct-group/root-0
grep: /tmp/0xff.z2MjAjJXuo/root/etc/group: No such file or directory
grep: /tmp/0xff.z2MjAjJXuo/root/etc/group: No such file or directory

This change prevent egetent() from attempting to lookup key if database
does not exit, removing error from output.

This change makes sense to me.

The "return 1" made me think about the return value a bit more. If we
want to replicate the behavior of getent from glibc, we should return
2 if the user/group does not exist or if the passwd/group files are
missing. I don't think any ebuild/eclass code really cares about the
specific status though, so we can leave that alone for now.
