zsh-completion: fix for #4318 (#4394) 

Escape unit names for the eval call in _call_program

The value of the Id property is transformed back into a unit name
usable by systemctl.
system-systemd\x5cx2dcryptsetup.slice -> system-systemd\x2dcryptsetup.slice

Also filter units by property via parameter expansion, not a for loop
