glsl/linker: Don’t check precision for shader interface
On GLES, the interface between vertex and fragment shaders doesn’t
need to have matching precision.
Section 4.3.10 of the GLSL ES 3.00 spec:
“The type of vertex outputs and fragment inputs with the same name
must match, otherwise the link command will fail. The precision does
not need to match.”
