bpf: test_maps: cleanup sockmaps when test ends
Bug: BPF programs and maps related to sockmaps test exist
in memory even after test_maps ends.
This patch fixes it as a short term workaround (sockmap
kernel side needs real fixing) by empyting sockmaps when
test ends.
Fixes: 6f6d33f3b3d0f ("bpf: selftests add sockmap tests")
