[Buildroot] [PATCH 1/1 v2] package/unscd: new package

A daemon which handles passwd, group and host lookups for running
programs and caches the results for the next query. You only need this
package if you are using slow Name Services like LDAP, NIS or NIS+.
This particular NSCD is a complete rewrite of the GNU glibc nscd which
is a single threaded server process which offloads all NSS lookups to
worker children; cache hits are handled by the parent, and only cache
misses start worker children, making the parent immune to resource
leaks, hangs, and crashes in NSS libraries.
It should mostly be a drop-in replacement for existing installs using
nscd.
