ENH: Improve module name extraction from wheel name for delvewheel fixup

The module name was previously obtained by removing the "itk-" prefix
from the wheel name. Some wheels might have suffixes, e.g.,
itk-rtk-cuda124. The module name is now obtained by
1. Removing the "itk-" prefix
2. Removing from the result everything after the first occurence of "-".
