muninlite: add some patches to address old issues

As muninlite doesn't appear to have had a release in a few years and activity
on the git repo appears to have stalled, we add some patches on our end for now.

Patches:

- 001->004 are upstream fixes from master.
- 100 is a submitted PR: https://github.com/munin-monitoring/muninlite/pull/19
  to fix https://github.com/munin-monitoring/muninlite/issues/14.
- 200->204 is a submitted PR to allow customizing the monitored network interfaces:
  https://github.com/munin-monitoring/muninlite/pull/18. Despite the large
  number of patches it is actually a trivial change.
