libgpiod: fix gpio-tools tests failure with new coreutils

openembedded-core updated to coreutils v9.10 in which commit
8c2461933411 ("timeout: honor ignored signal dispositions") changed the
behavior of timeout. It will no longer propagate SIGINT to background
shell jobs which breaks test-cases for gpio-tools which verify that they
exit correctly after receiving SIGINT. This backports the patch sent
upstream that removed the offending test-cases as we already have a
similar set of tests for SIGTERM.

+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.
