Pre-generate files in /library in libtestdriver1 components

We need this because `library/Makefile` and `libtestdriver1_rewrite.pl`
don't set things up properly in `tests/libtestdriver1/library`. The visible
symptom is that when not all generated files are present, the makefile looks
for `../framework/exported.make` which is not present. I have not gone down
this rabbit hole to see how much effort it would be to make it work.
