Subject: [PATCH] wipeout-rewrite: Housekeeping, fix gamecontrollerdb loading

- Enable __structuredAttrs & strictDeps
- Fix building under the latter
- writeShellScript -> writeShellApplication
  For build-time syntax checking
- Patch in path to gamecontrollerdb.txt from sdl_gamecontrollerdb
  With a build-time check for its existence, to make sure this doesn't silently bitrot
