Linux kernel versions 6.6.102-104 and 6.12.42-45 have a regression in /proc/net/tcp that causes seek operations to fail with "illegal seek". This breaks portlist tests on these kernels. Add kernel version detection for Linux systems and a SkipOnKernelVersions helper to tstest. Use it to skip affected portlist tests on the broken kernel versions. Thanks to philiptaron for the list of kernels with the issue and fix. Updates #16966 Signed-off-by: Andrew Dunham <andrew@tailscale.com>
