Added constant 1 to h1susmc2, as well as the M1 and M2 stages of HSTS_MASTER (which serves MC1 and MC3).  Also added 1s to the inputs of ZM1 and ZM2 in h1susopo, since they use the same HSSS_MASTER as the RMs and OMs.

Note that these models don't need restarting immediately with these changes, but when they are next built and restarted (which we're doing for an upcoming RCG upgrade) a DAQ restart will be required.

Pulled from LLO the MC_MASTER part, which they also use for their recycling cavities instead of RC_MASTER.  This is why I had to modify h1susmc2.

Also updated LLO's HSTS_MASTER (pulled the common part for them), and put in the constant 1 trigger overrides in l1susopo so they won't get errors next time they try to compile.
