SUSYBSMAnalysis/HSCP: fix Clang reported errors

`Hscp_hasTrack`, `Hscp_hasMuon` and `Hscp_hasRpc` are bool arrays (not
dynamically alloced). Bool conversion on the address of the array
will always return true.

I believe, the intention was to do, e.g., `Hscp_hasTrack[NHSCPs]`

**This is a guess based on the code, verify that the changes are correct before approving**

This is definitely a bug in the code.
