dns/dnsdist: Update to 1.4.0

• Lint Makefile
• Some configure switches changed from --enable to --with
• Rename FSTRM to DNSTAP
• Add DoH support
• Switch to LuaJIT-Openresty (when LUAJIT is selected instead of LUA)
• Remove unnecessary patch (files/patch-dnsdist-lua-vars.cc)
• Major improvement in the rc script: allowing multiple daemons
• Start using -C and %%ETCDIR%% causing the default path for dnsdist.conf changes to usually /usr/local/etc/dnsdist/ in which you can store single or multiple config files, includes, key-files for DNSCrypt, key/certs for DoH, etc.

Also, change maintainer to Ralf van der Enden.
