package/libgpiod2: security bump to 2.2.4

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
