packaging: use lower case for RC files

The file case doesn't matter. I'm not sure why it is
capitalized.

This is a source of inconsistency between Inno and WiX.
So let's standardize on the lower case names.

The MSI should remove the old files before installing
the new one, so there shouldn't be a problem with a case
collision.

And, users should not have modified these files, so it
should be safe to rename them.

'''helper extension to measure memory usage
