events 50.samba: also support suse and ubuntu/debain systems

for managing samba and winbind

This uses CTDB_INIT_STYLE as exported by ctdb.init.

suse systems usually have separate init scripts for
smb for smbd and nmb for nmbd, and the ubuntu/debian
start script for smbd and nmbd is called samba instead
of smb (on redhat).
