[Piglit] [PATCH 05/15] shader_runner: Allow struct version to represent ES versions

[Chad Versace]

* Add new field version::es.
* Add `bool es` to version_init() parameters.
* Update version_string() and version_compare().

Currently, version::es is always false and shader_runner does not parse ES
versions.
