Nougat IOT Release (Polk Assist)
Fix aarch64 test failure.

aarch64 doesn't have the legacy `open` syscall, only `openat`.

  libminijail[7803]: compile_file: policy(1): nonexistent syscall 'open'
  libminijail[7803]: compile_filter: compile_file() failed
  external/minijail/syscall_filter_unittest.cc:1195: Failure
  Expected equality of these values:
  res
  Which is: -1
  0

Switch to `read` instead, because every arch has always had `read`.

Bug: N/A
Test: ran arm and aarch64 tests manually
