B-physics trigger: fix multiplicity requirement for 'bTau' chains (ATR-23887)

The number of muons fitted to the common vertex should be equal to the total chain multiplicity in the case of 'bTau' topo. Also no need to check two muons have opposite charges in the case bTau is seeded from two L1 seeds.

All chains with 'bTau' are affected:

• 'HLT_mu11_mu6_bTau_L1MU8VF_2MU5VF'
• 'HLT_mu11_mu6_bTau_L1LFV-MU8VF'
• 'HLT_3mu6_bTau_L13MU5VF'
• 'HLT_2mu6_mu4_bTau_L12MU5VF_3MU3V'
• 'HLT_mu6_2mu4_bTau_L1MU5VF_3MU3V'
• 'HLT_3mu4_bTau_L13MU3V'
