selftest: tcp: Add v4-mapped-v6 cases in bind_wildcard.c.
We add these 8 test cases in bind_wildcard.c to check bind() conflicts.
1st bind() 2nd bind()

All test passed without bhash2 and with bhash2 and this series.
Before bhash2:
$ uname -r
6.0.0-rc1-00393-g0bf73255d3a3
$ ./bind_wildcard
...
# PASSED: 16 / 16 tests passed.
Just after bhash2:
$ uname -r
6.0.0-rc1-00394-g28044fc1d495
$ ./bind_wildcard
...
ok 15 bind_wildcard.v4_local_v6_v4mapped_local.v4_v6
not ok 16 bind_wildcard.v4_local_v6_v4mapped_local.v6_v4
# FAILED: 15 / 16 tests passed.
On net.git:
$ ./bind_wildcard
...
not ok 14 bind_wildcard.v4_local_v6_v4mapped_any.v6_v4
not ok 16 bind_wildcard.v4_local_v6_v4mapped_local.v6_v4
# FAILED: 13 / 16 tests passed.
With this series:
$ ./bind_wildcard
...
# PASSED: 16 / 16 tests passed.
