kernel: Remove support for kernel 3.18

No target is using kernel 3.18 anymore, remove all the generic
support for kernel 3.18.

The removed packages are depending on kernel 3.18 only and are not used on
any recent kernel.

-Subject: [PATCH] pppoe: Use workqueue to die properly when a PADT is received
-
-When a PADT frame is received, the socket may not be in a good state to
-close down the PPP interface. The current implementation handles this by
-simply blocking all further PPP traffic, and hoping that the lack of traffic
-will trigger the user to investigate.
-
-Use schedule_work to get to a process context from which we clear down the
-PPP interface, in a fashion analogous to hangup on a TTY-based PPP
-interface. This causes pppd to disconnect immediately, and allows tools to
-take immediate corrective action.
-
-Note that pppd's rp_pppoe.so plugin has code in it to disable the session
-when it disconnects; however, as a consequence of this patch, the session is
-already disabled before rp_pppoe.so is asked to disable the session. The
-result is a harmless error message:
-
-Failed to disconnect PPPoE socket: 114 Operation already in progress
-
-This message is safe to ignore, as long as the error is 114 Operation
-already in progress; in that specific case, it means that the PPPoE session
-has already been disabled before pppd tried to disable it.
