selftests/bpf: Fix memory leak caused by not destroying skeleton

Browse source 
Some test cases does not destroy skeleton object correctly, causing ASAN
to report memory leak warning. Fix it.

Fixes: 0ef6740e97 ("selftests/bpf: Add tests for kptr_ref refcounting")
Fixes: 1642a3945e ("selftests/bpf: Add struct argument tests with fentry/fexit programs.")
