emplp12.gms : Test solution quality with solvelink=3 using EMP

Description

This model tests lp12 from the Test Library with solver EMP. In the first test
EMP generates a standard scalar model which is solved by the default lp solver.
For the second test EMP rewrites the model as MCP and solves it with the default
MCP solver.
