DAHDI: Build fixes for various atypical systems.

* Slipstream unmerged patches addressing various critical build failures.
* Use proper flags based on detected version of wget. This fixes
  builds on Fedora 40, where wget2 is present instead of wget.
* Install specific kernel-devel version match if mismatched.
  This fixes builds on Fedora-based systems.
* Manually build makefw target in DAHDI Linux if tor2 driver is present,
  to prevent build failing due to missing target.
