mesa: GL_ARB_texture_storage is not optional

In Mesa, this extension is implemented purely in software.  Drivers may
*optionally* provide optimized paths.

NOTE: This has the side effect of enabling the extension in the radeon,
r200, and nouveau drivers.

v2: Minor whitespace tidying (suggested by Brian).
