Subject: [PATCH 01/20] compat ABI: use non-compat openat and open_by_handle_at variants

The only difference is that non-compat version forces O_LARGEFILE,
and it should be the default behaviour for all architectures, as
we don't support 32-bit off_t. The only exception is tile32, that
continues with compat version of syscalls.
