Several fixes and improvements in ejabberd.init.template

Changes:
* Set script as executable
* Add LSB tags and overrides, copied from Debian's ejabberd package
* Add chkconfig support (thanks to Ivan Martinez)(EJAB-1450)
* Don't use nounset, as that breaks when no argument is provided
* Add status command
