freedombox.maintscript: remove tahoe and mldonkey apache conf files
Currently, tahoe-plinth.conf and mldonkey-freedombox.conf are left over in FreedomBox systems that were installed on plain Debian. This commit makes sure these files are removed.
Test:
- I installed FreedomBox on Debian and checked if the obsolete files are indeed present.
- I built my own package with the modifications and updated FreedomBox with the local deb file.
