fix relative references for license and acks in installer build
...
The process of creating an installer involves building "racket-index"
in user scope, but the license and acks files are normally only in
installation scope. An explicit targeting of the installation-scope
output needs to be disabled when the documentats are rendered to
user scope.

fix optimizer bug related to single-use functions
...
Fix problem with once-use tracking and delayed variable-use marking
that is performed for local function bodies. A delayed variable-use
registration might happen after a once-used variable is replaced by
its use.
This scenario is difficult to provoke, because the optimizer has to
first decide not to move a once-use function, and in a latter pass
decide to move it after all. There's not enough information to
retract the tentative use plus its transitive implications.
The solution is to avoid the generic once-use layer for `lambda` forms
whose uses are delayed (and that likely has a good effect on inlining
anyway). The other half of the solution is to avoid transitive use
marking on a once-used variable whose expression has been moved (and
there are no transitive things to skip, because that expression isn't
a `lambda` form).
