Wrong shaders in glcParallelShaderCompileTests.cpp

Wrong shaders in glcParallelShaderCompileTests.cpp

In glcParallelShaderCompileTests.cpp:50
it is written as
"int main() {\n"

which is invalid as per spec.

As per spec GLSL 4.60, section 6.1 last paragraph:
It is a compile-time or link-time error to declare or define a function
main with any other parameters or return type.

in glcParallelShaderCompileTests.cpp:55

it is written as "out ver4 fragColor;\n"
it should be "out vec4 fragColor;\n"

there is no data type as "ver4"

Affects:
KHR-GL46.parallel_shader_compile.compilation_completion_parallel

Components: OpenGL

VK-GL-CTS issue: 1182
