libgpiod: update to v2.2.4

Bug-fix release addressing several issues discovered during an
AI-augmented security audit. The most severe bug was found in the C
extension code of the python bindings - which also get an update - but
there were some memory leaks and integer overflow bugs in the core C
library as well as in tools and DBus daemon.

Full changelog:

Bug fixes:
- fix buffer over-read bugs when translating uAPI structs to library types
- fix variable and argument types where necessary
- sanitize values returned by the kernel to avoid potential buffer overflows
- fix memory leaks in gpio-tools
- add missing return value checks in gpio-tools
- fix period parsing in gpio-tools
- use correct loop counter in error path in gpio-manager

Improvements:
- make tests work with newer coreutils by removing cases checking tools'
  behavior on SIGINT which stopped working due to changes in behavior of the
  timeout tool

Also: drop the patch that's now upstream from the recipe.

-Subject: [libgpiod][PATCH] tools: tests: remove SIGINT test cases
-
-In coreutils v9.10 (specifically with commit 8c2461933411 ("timeout:
-honor ignored signal dispositions")) the behavior of timeout changed and
-it will no longer propagate SIGINT or SIGQUIT in shell background jobs.
-This breaks the test cases checking the behavior of tools after SIGINT.
-We have to assume that if exit after SIGTERM works, then so does it
-after SIGINT and remove the failing tests.
