This game sets the reset isolation bit which causes the GL context
creation to fail as Mesa doesn't support the
GLX_ARB_robustness_application_isolation extension. Here we override
and clear the bit.

According to the spec says:

    "The GLX_ARB_robustness_application_isolation and
    GLX_ARB_robustness_share_group_isolation extensions do not provide
    guarantees for graphics resets caused by applications which did
    not create their contexts with both the LOSE_CONTEXT_ON_RESET_ARB
    reset notification strategy and the
    GLX_CONTEXT_RESET_ISOLATION_BIT_ARB bit."

And the game doesn't set LOSE_CONTEXT_ON_RESET_ARB so technically
we could ignore the reset isolation bit even if Mesa did support
the extension.
