Inotify: undefined reference to `anon_inode_getfd'

Fix:

fs/built-in.o: In function `sys_inotify_init1':
summary.c:(.text+0x347a4): undefined reference to `anon_inode_getfd'

found by kautobuild with arms bcmring_defconfig, which ends up with
INOTIFY_USER enabled (through the 'default y') but leaves ANON_INODES
unset.  However, inotify_user.c uses anon_inode_getfd().
