sandbox: Return error code from read/write/seek
The existing API for these functions is different from the rest of
U-Boot, in that any error code must be obtained from the errno variable
on failure. This variable is part of the C library, so accessing it
outside of the special 'sandbox' shim-functions is not ideal.
Adjust the API to return an error code, to avoid this. Update existing
uses to check for any negative value, rather than just -1.
