[Buildroot] [git commit] package/busybox: fix avahi-autoipd error message

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=3c5ca644ef8dbcccbc40fc3fc56b74bc54782ae4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When using a combination of udhcpc and avahi-autoipd in case of receiving IP
from a DHCP server, the following message can be seen:
"Failed to kill daemon: No such file or directory".
Add a check for a running avahi-autoipd to fix this issue.
