selftests/tc-testing: Add cls_route bucket move and change tests

Add 4 tdc tests for the cls_route bugs fixed earlier in this series:

- Delete a route filter that was moved to another bucket (a7d2):
  Validates that deleting a filter, and making a bucket empty, does not
  leave a dangling empty bucket
- Try to change a route filter onto an already used handle (c05a):
  Validates that attempting to change an existing filter's handle to an
  already taken one fails
- Replace a route filter that shares its key with another filter (3f21):
  Validates that an in-place replace keeps the handle userspace named
  the filter by, rather than dropping the 0x7F00 bits from it
- Replace both route filters sharing a key (9d0e):
  Validates that replacing one of the two does not make the other one
  unreplaceable
