configure: don't control egl version

The required version only corresponds to version of mesa implementation.
This mesa version requirement causes configure errors,
when weston is configured for a different egl implementation than mesa.
Because the version of the egl drivers are not alligned
to the mesa version.

Therefore, I deleted the version controlling for egl,
so that weston can be configured for a different egl implementation.
