[Piglit] [PATCH 2/2] varying-struct-centroid: Fix default precision qualifiers

[Iago Toral Quiroga]

Default ES precision qualifiers for float types in the VS and FS
are different and that should make the test fail to compile/link
if Mesa actually checked for these things (because it would realize
that VS outputs and FS inputs do not have the exact same type as
a consequence).

Fix this by setting the same default precision qualification for floats
in the VS and FS shaders.
