[PATCH] Move sighand_cachep to include/signal.h

Move sighand_cachep definitioni to linux/signal.h

The sighand cache is only used in fs/exec.c and kernel/fork.c.  It is defined
in kernel/fork.c but only used in fs/exec.c.

The sighand_cachep is related to signal processing.  So add the definition to
signal.h.
