[PATCH v200 wayland-protocols] test: add make check

[Quentin Glidic]

From: Derek Foreman <derekf at osg.samsung.com>

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

Just added AC_ARG_VAR to allow overriding the variable when calling configure.
