wined3d: Report the correct number of available 4-component float vectors for GLSL

[H. Verbeet]

GL_MAX_VERTEX_UNIFORM_COMPONENTS_ARB and
GL_MAX_FRAGMENT_UNIFORM_COMPONENTS_ARB return the number of available
uniform components. A 4-component float vector need 4 uniform
components.

Changelog:
  - Report the correct number of available 4-component float vectors for GLSL
