Revert "Fix selinux problems on vhost"

We are reverting as this breaks our gitXX.o.o servers, which are centos-7. EG:

  (/Stage[main]/Cgit/Httpd::Vhost[git.openstack.org]/Exec[update_context_MEANINGLESS ARGUMENT]/returns) chcon: cannot access ‘MEANINGLESS’: No such file or directory

This reverts commit 10844f7c9e.
