[PATCH wayland-protocols] test: add make check

[Derek Foreman]

We can now test all the protocol files by running make check (or distcheck)
which will pass them through the scanner.

Changes from v1:
Use #~/bin/sh -e and drop the && from each line in the script
Discover the scanner's location and use it
