loadbrm.py uses lower case smcat when it should be upper case

During the improvements to cmapi, mcs-loadbrm.py.in was changed to use a variable SMCAT to hold the path and file name of the executable smcat. Somewhere in the code (line 126), the name was wrongly written in lower case. Since python is a case sensitive language, this causes errors trying to run that line of code, which only happens for single server installations.
