backoff_db creation

[Jeffrey M. Vinocur]

As per TODO:

* If backoffdb is set in inn.conf and that directory doesn't exist, nnrpd
  refuses to start.  Either the directory should be created by the install
  process or nnrpd should just create it if it can.

Didn't get exhaustive testing -- somebody more familiar with file control
stuff in C should look at it to make sure I didn't do anything really
dumb.

Also, I didn't think about what permissions backoffdb should have, so it
just takes whatever the umask wants...that may not be right.
