selftests/bpf: Add CO-RE relocs kfunc flavors tests
This patch adds selftests that exercise kfunc flavor relocation
functionality added in the previous patch. The actual kfunc defined
in kernel/bpf/helpers.c is:
struct task_struct *bpf_task_acquire(struct task_struct *p)
The following relocation behaviors are checked:
struct task_struct *bpf_task_acquire___one(struct task_struct *name)
* Should succeed despite differing param name
struct task_struct *bpf_task_acquire___two(struct task_struct *p, void *ctx)
* Should fail because there is no two-param bpf_task_acquire
struct task_struct *bpf_task_acquire___three(void *ctx)
* Should fail because, despite vmlinux's bpf_task_acquire having one param,
the types don't match
