[libgl1-nvidia-glx] not providing libgl1

[Diego Joss]

Hello,

I have noticed a discrepancy in the package libgl1-nvidia-glx. I hope
this is not an error from my side.

In testing (wheezy), the package libgl1-nvidia-glx (version 275.09.07-1)
for nvidia graphics cards does not contain a "Provides:" with "libgl1"
(as with the package "libgl1-mesa-glx"), thus several dependencies are
now broken (when using libgl1-nvidia-glx to provide the binary OpenGL
libraries).

Thank you for all your work,
Diego Joss
