beta: ensure /usr/local/apache* belong to mwdeploy

The Jenkins jobs are running on deployment-bastion.pmtpa.wmflabs and
require the Apache directories to belong to mwdeploy user.  Since
misc::deployment::vars is applied on different instances each having a
different UID for 'mwdeploy', the directories kept changing of owner
which break Jenkins jobs :(
