Subject: [PATCH v5.15.y 2/4] samples: Make fs-monitor depend on libc and headers

From: Gabriel Krisman Bertazi <krisman@...labora.com>

[ Upstream commit 8fc70b3a142f97f7859bf052151df896933d2586 ]

Prevent build errors when headers or libc are not available, such as on
kernel build bots, like the below:

samples/fanotify/fs-monitor.c:7:10: fatal error: errno.h: No such file
or directory
  7 | #include <errno.h>
    |          ^~~~~~~~~
