Hi bitlbee can be run ad deamon now !
for security reason its run as user bitlbee.
here is a full list of changes i did there:

- Added init.d and systemd to be able run the bitlbee as standard service.
- Rc$service script is runnig as symlink for systemd and init.d.
- Improved way how user bitlbee is add into system via rpm.
- Fixed warning about wrong license:
its still "GNU General Public License version 2 (GPL v2)" but osc marks it
via shorcut : GPL-2.0+
- The PID directory is /var/run/bitlbee/ or /run/bitlbee/ depends on the version.
- The PID directory is created via systemd or initd script, bacuse its in tmpfs.
- Each BuildRequires is on one line to avoid duplicate packages.
- Removed if for SLES9 - not need any more
- Run spec-clean on the spec file and fixed a small bug is spec file after clearing no "fixme" any more there.

ps : the warning bitlbee.x86_64: W: call-to-mktemp /usr/sbin/bitlbee need to be patch in future, however my C skills are very low ....
