pwdgrp.c: Change to simply ignore return value from mkdir(/etc)

At this point in time, /etc can be created in multiple ways. There
is a discussion (#4354) that would define a mechanism for
instantiating a base file system with some flexibility for the
set of directories included. For now, this particular mkdir()
call can fail because /etc could already have been created by
at least an initial filesystem image, the shell, or libbsd.

closes #4382.
