[oe] [meta-networking][PATCH] postfix: fix postinstall to avoid do_rootfs failure

[Chen Qi]

When lsb is enabled, that is, 'linuxstdbase' is in OVERRIDES,
do_rootfs would fail if both 'msmtp' and 'postfix' are installed.
This is because they both try to create /usr/lib/sendmail link if
it does not exist. So we need to fix the check to avoid non-zero
exit status.
