selftests/bpf: Fix verifier_arena_globals1 failure with 64K page

Browse source

With 64K page on arm64, verifier_arena_globals1 failed like below:
  ...
  libbpf: map 'arena': failed to create: -E2BIG
  ...
  #509/1   verifier_arena_globals1/check_reserve1:FAIL
  ...

For 64K page, if the number of arena pages is (1UL << 20), the total
memory will exceed 4G and this will cause map creation failure.
Adjusting ARENA_PAGES based on the actual page size fixed the problem.
