[PATCH xserver] configure.ac: bump epoxy requirement to 1.2

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

As pointed out in the ABI tracker[1], epoxy has gone through a few
non-backwards compatible ABI changes, yet preserved the DSO name.

Most noticeable of which, from xserver POV, in epoxy_has_egl_extension()
- s/EGLDisplay */EGLDisplay/.

To avoid unwanted/unexpected 'fun' behaviour, just bump the requirement.
Version 1.2 has been released more than 2 years ago, in May 2014.

We might want this in the stable branch(es)?

Eric, iirc Dave had some ideas about moving libepoxy to fd.o [+ making
it the canonical/upstream source] and was looking for your blessing.

How is that going ? The state of the github repo looks tragic.
