Check percpu map value size first and add the test case in selftest.

Change list:
- v1 -> v2:
    - round up map value size with 8 bytes in patch 1
    - add selftest case in patch 2

Tao Chen (2):
  bpf: Check percpu map value size first
  bpf/selftests: Check errno when percpu map value size exceeds
