Subject: [PATCH] Call glGetProgramiv to retrieve program log length

Calling glGetShaderiv to retrieve the program log length produces a
GL_INVALID_OPERATION error and length < 0, preventing the return of the
actual info log. This fix replaces the call to glGetShaderiv with
glGetProgramiv.

Closes #4659
