This fixes two issues with the freeradius package init scripts:

- The package installs libraries in /usr/lib/freeradius{2,3}, but the
  musl dynamic linker won't find them there unless LD_LIBRARY_PATH is
  set to include this directory. This adds an appropriate env statement
  to the procd init setup.

- procd expects services to stay in the foreground, or it will be unable
  to properly shut them down again. This adds the -f flag to radiusd to
  achieve that.

The initscript originally imported from oldpackages no longer does
the job, sed'ery around ifconfig is just not the way.
Remove stuff which can also be done via /etc/freeradius2/* or
/etc/default/radiusd instead.

Fixes #1769 and #1193
