selftests/tc-testing: add u32 manual table handle IDR tests

Browse source

35fc: create a manual table with handle 801:, then add an auto-allocated
table. Before the fix, the auto allocation reuses id 1 and hands out the
same handle 0x80100000, aliasing the manual table; the test requires the
manual 801: handle to keep exactly one entry in the dump.

a6e8: with a live u32 table keeping the tc_u_common alive, add and delete
a manual table with handle 901:, then re-add it. Unpatched, the delete
leaks the raw-keyed IDR entry and the re-add fails with -ENOSPC; the
test requires the re-add to succeed.
