[Piglit] [PATCH 2/2] glx: Replace glFlush calls with glFinish

[Paul Berry]

Currently, in Mesa with the i965 driver, calling glFlush() forces all
pending drawing operations to be sent to the kernel; this ensures that
any subsequent drawing operations will be performed after those
pending drawing operations, even if they come from other contexts.
The glx-multithread test was relying on this behaviour, however, the
GL and GLX specs do not garantee this.

This patch modifies the glx-multithread test to use glFinish() instead
of glFlush().
