Fix ref to src ctl

[pratheekshasn]

#297

A couple of VIs still had references to the source lvsupport.lvlib, which caused the lvlib and a couple of typedefs to get pulled into the installed grpc-labview code. The following files have been fixed to have references to the release version of the lvlib instead (lvsupport-release.lvlib):

1. Get package_template_enum.vi - replaced indicator with the right reference
2. Server gRPC UEs.ctl
3. ServiceName Template.lvclass - replaced the private data control with the right reference
