shell-completion: replace printf with echo

It is faster to use a bash built-in, then to invoke an external
program. The problem of unit names starting with a dash is solved
by prepending a space. Spaces are ignored anyway.

For zsh, replace echo "$unit", which is vulnerable to dashes,
with echo " $unit".
