utility class for setting the target platform

This is required when running SwtBot tests in Tycho that requires the
PDE, for example, for testing that the imported projects compile fine,
or if they use the DSL, which requires PDE projects dependencies.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=343156
