[Piglit] [PATCH 1/2] glslparsertest: Added some few more struct construction tests

[Andres Gomez]

This set focus on checking invalid structs construction. Specifically,
adds a test to check that only implicit conversions are perform and
vector conversions of the type vec3 to vec2 through dropping the z
component are not allowed.
