selftests/bpf: Add kfunc_call test for simple dtor in bpf_testmod
add simple kfuncs to create/destroy a context type to bpf_testmod,
register them and add a kfunc_call test to use them. This provides
test coverage for registration of dtor kfuncs from modules.
By transferring the context pointer to a map value as a __kptr
we also trigger the map-based dtor cleanup logic, improving test
coverage.
