BnoC HLT2 lines -- tune existing BdsToKstzKstzb and BdsToKstzRho lines and add new BdsToRhoRho and BdsToPhiRho lines

This MR tunes the rates/efficiencies of the BnoC HLT2 lines BdsToKstzKstzb and BdsToKstzRho lines and adds two lines missing from the set of charmless B->VV lines, BdsToRhoRho and BdsToPhiRho.

Line	Incl. Rate (kHz)	Excl. Rate (kHz)	Eff. (%)
BdsToKstzKstzb	0.14334 \pm 0.0223	0.09439 \pm 0.0181	39 \pm 2
BdsToKstzRho	0.13635 \pm 0.0218	0.08390 \pm 0.0171	35 \pm 2
BdsToPhiRho	0.00349 \pm 0.0034	0.0 \pm 0.0	37 \pm 2
BdsToRhoRho	0.08041 \pm 0.0167	0.05244 +/- 0.0135	34 \pm 2
Total:	0.318 \pm 0.033	-	-

The rates are estimated from 50000 HLT1-filtered minbias events. The efficiencies are estimated on the following vector-vector MC samples for each line:

• BdsToKstzKstzb -- 13104001 -- B_s^0 \to K^*(892)^0 \bar{K}^*(892)^0
• BdstoKstzRho -- 11104041 -- B^0 \to K^*(892)^0 \rho(770)^0
• BdsToPhiRho -- 13104051 -- B_s^0 \to \phi(1020) \rho(770)^0
• BdsToRhoRho -- 11104061 -- B^0 \to \rho(770)^0 \rho(770)^0

The changes made in basic_builder.py add optional arguments to the Kstar, phi and rho builders and so will not affect existing lines already using these builders.

Overlaps

This is cross-posted from !2388 (merged) where the overlaps are checked w.r.t. 4h lines which have the same final state as these VV lines.
