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 are going to drop the support of 32-bit userspace off_t. The exception is tile32 that continues with compat version of syscalls.
