Linux v4.11: signal stuff moved to sched/signal.h

Browse Source 
In Linux commit c3edc4010e9d102eb7b8f17d15c2ebc425fed63c, signal_struct
and other signal handling declarations were moved from sched.h to
sched/signal.h.

This breaks existing OpenAFS autoconf tests for recalc_sigpending() and
task_struct.signal->rlim, so that the OpenAFS kernel module can no
longer build.

Modify OpenAFS autoconfig tests to cope.
