fix `#lang errortrace'

Browse Source 
Since `#lang errortrace' annotates the result of `local-expand',
 it needs to handle `letrec-syntaxes+values', as well as allowing
 `#%expression' in more places.

 This change relies on a change to `kernel-syntax-case'. This
 isn't a new bug, and it's ok to not include it in 5.1.2
 (especially since the `kernel-syntax-case' change should not be
 merged).
