Compatibility fix: use absolute path to FlexibleSUSY.m module

Sophie Underwood had problems loading the FlexibleSUSY` module via

  Needs["FlexibleSUSY`", "FlexibleSUSY.m"];

This fix uses the absolute path to the FlexibleSUSY.m file

  Needs["FlexibleSUSY`", "meta/FlexibleSUSY.m"];

which solves the problem on Sophies machine.
