generate systemd: quote arguments with whitespace

Make sure that arguments with whitespace are properly quoted so they are
interpreted as one (and not multiple ones) by systemd.

Now `-e tz="america/new york"` will be generated as `-e "tz=america/new york"`.
The quotes are moving but the argument is still correct.
