mesa/main: simplify pipeline-statistics query validation

The _mesa_has_ARB_pipeline_statistics_query(ctx)-helper will already
check the GLES-version according to the extension-table, so if this
extension would ever be back-ported to ES, we only need to update the
table to support this.

This shouln't have any functional effect.
