gnu: chez-scheme-for-system: Adjust for bytecode backend.
Change 'chez-scheme-for-system' to return 'chez-scheme-for-racket' in
two cases when it previously returned 'chez-scheme':
1. When 'chez-scheme' is not distributed with bootstrap bootfiles,
since we can only cross-compile 'chez-scheme' for those systems; and
2. When neither 'chez-scheme' nor 'chez-scheme-for-racket' supports
native code generation, since we will be able to use the ``portable
bytecode'' backends of 'chez-scheme-for-racket' as soon as the
issues in <https://racket.discourse.group/t/950> are resolved.
* gnu/packages/chez.scm (chez-scheme-for-racket): Change condition.
