db: ignore implicit-int and implicit-function-declaration issues fatal with gcc-14jansa/master

* many configure tests (which might not fail before) are failing with gcc-14:

* I have noticed this on db-native build on host with gcc-14
  where it caused fatal do_configure error:
  http://errors.yoctoproject.org/Errors/Details/784164/

  checking for mutexes... UNIX/fcntl
  configure: error: Support for FCNTL mutexes was removed in BDB 4.8.

  the config.log confirms it's because implicit-int:
