Eliminate run-time system crash in code:load_abs/1

The run-time system would terminate if code:load_abs/1 was
called with a filename containing any non-latin1 characters.
The reason is that code_server would attempt to construct a
module name from the filename using list_to_atom/1 and that
atoms currently are limited to the latin1 character set.

But how should the error be reported?

I have decided to that the simplest and least confusing way
is to move the call to list_to_atom/1 to 'code' module and
let it crash the calling process. The resulting stack back
trace will make it clear what the reason for the crash was.
