[gtk-doc] check: fix check invocation with env-vars

[Stefan Kost <stefkost src gnome org>]

commit eb70b07faab9b863cd70ee0d4e3b5566e214ec01

    check: fix check invocation with env-vars
    
    We need to first cd and then set env-vars so that the vars are active for the
    process. Also pick the chance and pass srcdir + builddir (needed for transition
    of building in builddir).
