selftests/bpf: Add tests for bpf_task_from_vpid() kfunc
This patch adds test cases for bpf_task_from_vpid() kfunc.
task_kfunc_from_vpid_no_null_check is used to test the case where
the return value is not checked for NULL pointer.
test_task_from_vpid_current is used to test obtaining the
struct task_struct of the process in the pid namespace based on vpid.
test_task_from_vpid_invalid is used to test the case of invalid vpid.
test_task_from_vpid_current and test_task_from_vpid_invalid will run
in the new namespace.
