at: allow normal user to use 'at'

fix [BUGID #675]

Similar to previous cronie changes, so far 'at' environment is also not
complete and only root user could trigger delayed tasks. Similar permission
changes are required for:
	/etc/at.deny
	/usr/bin/at
	/var/spool/at/

/usr/bin/at is setgid to 'daemon', to differentiate with cronie. So move
'at' out of 'cron' (/var/spool/cron/at -> /var/spool/at)

another fix is to rename /etc/init.d/at to atd which is more widely used
in other distros (also required by LTP test cases)
