Subject: [PATCH -next] samples: watch_queue: depends on HEADERS_INSTALL

From: Randy Dunlap <rdunlap@...radead.org>

Building samples/watch_queue/ uses installed headers, so make it
depends on HEADERS_INSTALL to prevent a build error.

../samples/watch_queue/watch_test.c:23:10: fatal error: linux/watch_queue.h: No such file or directory
