/etc/init.d/munin has two broken function definitions

[Travis Bean]

Munin 2.0.57-1ubuntu2 fails to install on Ubuntu Server 22.04. This appears to the the exact same bug patched in Debian upstream (i.e., https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=954234), but for some reason, this patch never made its way to the Ubuntu Server mirrors. Please review above mentioned Debian bug report, as I just confirmed this exact same issue.

Here is the failure:

This is all that needs to be patched:

sed -i "s|true|{ true ; }|" /etc/init.d/munin

Status changed to 'Confirmed' because the bug affects multiple users.
