Previously, when user tried start corosync-qnetd without
initialized NSS database then generic (not very helpful
and misleading) NSS error was logged
"NSS error (-8015): The certificate/key database is in an old,
unsupported format.".
Solution is to check if it's possible to open NSS DB directory and
display (usually much more informative) result of strerror function.
Such check is called before fork, so init system can return error code
during start.
