winsdk: Fix multiple RT uninstall issue

Change originally by David Pinedo.  If the same Vulkan Run-time
installer is executed multiple times, it will bump the install count
for the RT installation.  There was a problem during uninstall
which failed to look at the install count and would always remove
some important files.  This fixes that issue.
