faa670d3862783017f5cd1491f37648e1875f19f test: Properly set BIP34 height in CreateNewBlock_validity unit test (MarcoFalke)

Pull request description:

  The coinbase scriptSig in this unit test has several issues:

  * The BIP34 height is not the "first item" as required (See https://github.com/bitcoin/bips/blob/master/bip-0034.mediawiki#specification)
  * It uses the wrong encoding ( See da69d9965a/src/validation.cpp (L3250) )
  * It uses the wrong height (off by one)

  While BIP34 isn't currently enforced in this unit test, this should be fixed to avoid confusion and to promote self-consistency.

  The change obviously requires new proof of work (`BLOCKINFO`).

  Also change the block version from `1` to `VERSIONBITS_TOP_BITS`, because this test shouldn't care about the block version and bumping it is required for other changes.
