   Rather than use // IWYU pragma: keep with every #include <bitcoin-build-config.h>, apply a dedicated always_keep pragma to the bitcoin-build-config.h header itself.
2. iwyu: Add `pragma: always_keep` to `bitcoin-build-config.h` 39d868a9b1
3. scripted-diff: Drop now redundant `// IWYU pragma: keep`

   -BEGIN VERIFY SCRIPT-
   sed -i "s|#include <bitcoin-build-config.h> // IWYU pragma: keep|#include <bitcoin-build-config.h>|g" $( git grep -l "#include <bitcoin-build-config.h>" ./src/ )
   -END VERIFY SCRIPT-
