tests: Forbid to run the blit tests with count of 1

Browse Source 
Invoking say,

  sudo ./tests/gem_render_linear_blits 1

does not make a lot of sense as we're creating a single bo. The test
does not yell at you and passes, even if the rendercopy function does
not do anything. This makes it quite harmful when trying to debug
rendercopy without realizing that count is the number of allocated bos
and must be >= 2.
