tests/kms_flip: Check if is Intel device before doing all the setup

The tests bo-too-big and bo-too-big-interruptible should only run on
Intel devices. Instead of checking this condition after doing all the
setup, check this condition in the beginning of the test.

Checking if is an Intel device in the beginning of the test will also
avoid the following error, which occurs in non-Intel devices when
running the test bo-too-big:
