[waffle] [PATCH 2/3] examples: make use of waffle_teardown

[Emil Velikov]

Using this we clear the global state thus the user can call waffle_init()
multiple times, as things won't get clobbered.
According to gl_basic we cleanup ~20K of leaks (still reachable) and catch
a bug in the GL/dri2 loader :-)

Before:
    definitely lost: 63 bytes in 4 blocks
    still reachable: 43,695 bytes in 116 blocks

After:
    definitely lost: 87 bytes in 5 blocks
    still reachable: 23,451 bytes in 55 blocks
