eal/windows: allow running as non-admin
eal/windows: allow running as non-admin

Currently, since there is no runtime directory set, the code tries to
create a file in C:\ which is only writable with administrator
privileges. As a result, if the user is not admin, the application will
fail.
So, forcing no_shconf to 1 to prevent the code having to create files in
the runtime directory.
