configure: Add a minimum required version for the wayland package

Browse Source 
Previously Cogl would accept any version of Wayland when building the
Wayland backend. Seeing as there is now a stable API we might as well
specify that we require at least version 1.0.0. This is now also
mentioned in the README. This patch also changes it to use
PKG_CHECK_MODULES instead of PKG_CHECK_EXISTS because it does need to
abort if it fails and it shouldn't be checking it silently.

you will need the latest GL headers which can be obtained from:
