[ Impact ]

falcosecurity-scap-dkms does not compile from source in Noble with
kernel 6.11:

/var/lib/dkms/scap/0.15.1/build/main.c: In function ‘drop_nostate_event’:
/var/lib/dkms/scap/0.15.1/build/main.c:1653:22: error: implicit declaration of function ‘fd_is_open’; did you mean ‘finish_open’? [-Werror=implicit-function-declaration]
 1653 |                     !fd_is_open(close_fd, fdt)
      |                      ^~~~~~~~~~
      |                      finish_open

[ Test case ]

Install the latest linux-6.11 kernel on Noble:

$ sudo add-apt-repository ppa:canonical-kernel-team/ppa
$ sudo apt update
$ sudo apt install linux-image-6.11.0-12-generic \
                   linux-modules-6.11.0-12-generic \
                   linux-modules-extra-6.11.0-12-generic \
                   linux-headers-6.11.0-12-generic

Install falcosecurity-scap-dkms:

$ sudo apt install falcosecurity-scap-dkms

Load the module:

$ sudo modprobe scap

[ Fix ]

Patch the code to properly support the new linux 6.11 ABI.

[ Regression potential ]

A regression is unlikely due to the limited scope of the patch.
