[packages] avahi fix for Ticket #11039 -- rlimit-nproc set too low
This patches the /etc/avahi/avahi-daemon.conf file, setting the rlimit-nproc parameter to 3.
Thepresent value for rlimit-nproc of 1 is too low and  can cause the avahi-daemon to refuse to start, with a message:
chroot.c: fork() failed: Resource temporarily unavailable

This patch changes the setting of rlimit-nproc to 3, the same setting as
is in the default avahi-daemon.conf file.

The issue was reported in Ticket #11039.
