cleanup usr.sbin.nscd profile

From: Kshitij Gupta <kgupta8592@gmail.com>

This patch removes rules covered by abstractions in nscd profile:
- the network rules are in abstractions/nameservice
- @{PROC}/filesystems is in abstractions/base
- /{,var/}run/avahi-daemon/socket is in abstractions/nameservice
- /tmp/.winbindd/pipe and /var/lib/samba/winbindd_privileged/pipe are
  in abstractions/winbind via abstractions/nameservice
