Follow-up to issue #81: remove SysV shared memory IPC altogether

This change removes a long standing kernel requirement and architectural
mishap in the design of Finit v1.  It is no longer necessary to include
CONFIG_SYSVIPC in the kernel to use Finit and its command line tool
initctl.  It is also no longer possible to connect to the internals of
PID 1 using shmat(), the initctl tool has already been updated to use
the domain socket API.
