makefile: add options for other DBs (#5357)

## Description

This PR adds support for badgerdb, rocksdb and boltdb within the build options. 

RocksDB builds correctly.

```
 make build TENDERMINT_BUILD_OPTIONS=rocksdb    
CGO_ENABLED=1 go build -mod=readonly -ldflags "-X github.com/tendermint/tendermint/version.GitCommit=`git rev-parse --short=8 HEAD` -s -w " -trimpath -tags 'tendermint rocksdb' -o build/tendermint ./cmd/tendermint/
