setup: exclude some internal UCRT files
When attempting to build the Inno installer locally, I was getting
several file not found errors when py2exe was crawling DLL
dependencies. The missing DLLs appear to be "internal" DLLs
used by the Universal C Runtime (UCRT). In many cases, the
missing DLLs don't appear to exist on my system at all!
Some of the DLLs have version numbers that appear to be N+1
of what the existing version number is. Maybe the "public" UCRT
DLLs are probing for version N+1 at load time and py2exe is
picking these up? Who knows.
This commit adds the non-public UCRT DLLs as found by
py2exe on my system to the excluded DLLs set. After this
change, I'm able to produce an Inno installer with an
appropriate set of DLLs.
