[PATCH] kdb: include header in signal handling code

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

kdb_send_sig() is defined in the signal code and called from kdb,
but the declaration is part of the kdb internal code.
Include this from signal.c as well to avoid the warning:

kernel/signal.c:4789:6: error: no previous prototype for 'kdb_send_sig' [-Werror=missing-prototypes]
