    ci: Switch to rawhide
    
    While F26 satisfies all our build dependencies (not least because
    there's little to build), rawhide is much closer to the platform
    we are actually developing for, in particular when it comes to gjs
    and Spidermonkey.
    
    Also rawhide's mozjs52-devel package now includes the js52 binary,
    so we can run the basic syntax check added in commit 65a2099 during
    continuous integration.
