Subject: [PATCH -next] samples: Define dummy __NR_keyctl if undefined

mips:allmodconfig fails to build.

samples/watch_queue/watch_test.c: In function ‘keyctl_watch_key’:
samples/watch_queue/watch_test.c:34:17: error: ‘__NR_keyctl’ undeclared

Declare dummy __NR_keyctl if it is undefined to fix the problem.
