dri_util: Don't assume __DRIcontext->driverPrivate is a gl_context

The driverPrivate pointer is opaque to the driver and we can't assume
it's a struct gl_context in dri_util.c.  Instead provide a helper function
to set the struct gl_context flags from the incoming DRI context flags.

v2 (idr): Modify the other classic drivers to also use
driContextSetFlags.  I ran all the piglit GLX_ARB_create_context tests
with i965 and classic swrast without regressions.
