Fix shader draw parameter pack alignment issue

The test allocates a buffer of width*height*3 elements and expects
the readPixels to only write to this memory.

This is not correct if the window width is not a multiple of 4

Adding a gl.pixelStorei(GL_PACK_ALIGNMENT, 1) before the readPixels
fixes the issue

Affects:

KHR-GL45.shader_draw_parameters_tests.ShaderDrawArraysParameters

Components: OpenGL

VK-GL-CTS issue: 477
