[package] babeld: update to 0.98, fix scripts

- Full-featured UCI configuration file (no need for babeld.conf).
- Do not check the pid file (useless) and ahcpd script (harmful).
- Make /etc/config/babeld a config file.
- Launch at most one instance of babeld.
- Add status and reload options to init script.
- 8 February 2010: babeld 0.98:
  * Implement the ability to prefer Babel routes to external routes
    according to the kernel priority (-A).
  * Implement the ability to redistribute "boot" routes when the
    protocol is explicitly specified on the "redistribute" line.
  * Allow trailing whitespace in config file.
