selftests: tc-testing: add u32 node ID pool exhaustion test
Add a tdc test case that fills the u32 node ID space with 4095
auto-generated handles, then attempts to add a 4096th. On the fixed
kernel the 4096th filter is rejected with ENOSPC (exit 2). On the
unfixed kernel it silently succeeds with a duplicate handle.
The setup pipes the 4095 add commands directly into `tc -b -` inside a
single bash -c (matching the existing test id 1234 pattern), avoiding
any temp file.
