[build] Avoid deleting config header files if build is interrupted
With extremely unlucky timing, it is possible to interrupt a build and
cause make to delete config/named.h (and possibly any local
configuration headers).
Mark config/named.h and all local configuration headers as .PRECIOUS
to prevent make from ever deleting them.
