Changes v2 => v3:
1. Avoid using x86 only function in selftests. (Yonghong)
2. Add struct file and struct vm_area_struct to btf_task_struct_ids, and
   use it in bpf_find_vma and stackmap.c. (Yonghong)

Changes v1 => v2:
1. Share irq_work with stackmap.c. (Daniel)
2. Add tests for illegal writes to task/vma from the callback function.

3. Other small fixes.

Add helper bpf_find_vma. This can be used in some profiling use cases. It
might also be useful for LSM.
