[PATCH v4 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.

I haven't kept any RBs as this has changed significantly since anyone
reviewed it.

Changes:
v2:
Use #/bin/sh -e and drop the && from the script
Discover the scanner's location and use it
v3:
use dist_check_SCRIPTS instead of EXTRA_DIST
add the stable protocols as an empty var
v4:
Make configure check for host/build mismatch to avoid running target
 arch scanner when cross compiling
Make configure actually set the wayland_scanner var if we got it
 from pkg-config
Make the test script print an error if the scanner var isn't set
