initscripts global change

[Elan Ruusamäe]

what you think of this change?
it will make global $PROG (varname could be debated), 
which means always same service name regardless of invocation:

/sbin/service httpd
/etc/rc.d/init.d/httpd
/etc/rc.d/rc2.d/K15httpd

and propagates more /sbin/service usage
(which is preffered as it cleans up $ENV for invoked daemons)
