[OE-core] [PATCH] avahi: restore rlimit-nproc tweak for avahi discovery

[Zhixiong Chi]

Looks like we are still falling victim to:
   "chroot.c: fork() failed: Resource temporarily unavailable) = 57"
So we restore the removal of rlimit-nproc in avahi.conf, and could
receive return value from daemon process to start avahi-daemon.service
successfully.

The original patch is from
