gh-139310: skip test_aead_aes_gcm for Linux kernel between 6.16.0 and 6.17.x (#139552)

Currently, Fedora 42 uses a custom Linux Kernel 6.16.9 that backported an upstream change from 6.17-rc7 [1,3] but not its subsequent fix [2]. Until the issue is resolved upstream, we skip the failing test `test_socket.test_aead_aes_gcm` for kernel versions between 6.16 and 6.17.x. [1] torvalds/linux@1b34cbb [2] torvalds/linux@d0ca0df.
