guard known-driver suffix compare in windows_get_registry_files

[aizu-m]

windows_get_registry_files matches the tail of each registry driver name against the known-driver table via name + strlen(name) - strlen(filename), which points before the name buffer when a registry name is shorter than the filename, so the tail compare now runs only when the name is at least as long as the filename.

There seems to be some issue with the macOS CI tests. I tried to reproduce it locally but after 2 hours couldn't. I fear it is something specific to the runner environment that I couldn't determine. Regardless, the crash seems to have showed up in 9512907 as the build runs ctest to query the available tests. But that is my suspicion, not a proven statement.

CI Vulkan-Loader build # 3646 passed.

Its an upstream CMake issue.
https://gitlab.kitware.com/cmake/cmake/-/work_items/27972 Edit: similar but not the most closely matching issue. That would be https://gitlab.kitware.com/cmake/cmake/-/work_items/27939

I'm going to ignore it because it'll likely be fixed in the next CMake release that gets picked up by the github actions runner.

thanks for merging this, and for chasing the macOS CI noise down to the upstream CMake issue.
