Disable mod_deflate on XMLENT filtered files

Default configs for Ubuntu, at least, enable mod_deflate too broadly, and
XMLENT filtering needs to happen before mod_deflate kicks in.

Because we can't change the filter order, instead disable mod_deflate for
those files we have enabled XMLENT filtering, by use of the no-gzip ENV.
