build: fix configuring when building depends with NO_BDB=1

Currently, if you build depends using `NO_BDB=1` (only sqlite wallets),
./configure will fail as it still tries to find bdb. i.e:
```bash
checking for Berkeley DB C++ headers... default
configure: error: Found Berkeley DB other than 4.8, required for portable BDB wallets (--with-incompatible-bdb to ignore or --without-bdb to disable BDB wallet support)
```

This PR fixes the build such that you can build depends, opting out of
bdb without opting out of wallets entirely, and still configure
successfully.
