Disable split static postgresql outputs

In it's current state, we're unable to build cardana-chain-gen:

    cannot find -lpgcommon: No such file or directory
    cannot find -lpgport: No such file or directory
    collect2: error: ld returned 1 exit status

Remove the extra configure flags, and see if we can still build all the
other artifacts.
