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

[Guenter Roeck]

mips:allmodconfig fails to build.

samples/watch_queue/watch_test.c: In function âkeyctl_watch_keyâ:
samples/watch_queue/watch_test.c:34:17: error: â__NR_keyctlâ undeclared

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