Comment (by d3m0nkingx):

 I was able to resolve the RLIMIT_MEMLOCK permission issue for enabling
 tor's 'DisableAllSwap 1' option:

 To fix this it required to modify systemd's control groups memory
 management by doing the following at command line:

 $ systemctl set-property tor.service !MemoryAccounting=true

 then in the tor.service file add then:

 LimitMEMLOCK=infinity

 or some limit where the measurement is in bytes in increments of 1024.

 Afterwards, do systemctl daemon-reload; system service tor restart
