unit: printf specifiers %u and %h: $USER and $HOME.
These printf specifiers allow us to refer to $HOME and $USER in unit files. These are particularly helpful in instanced units that have "User=" set, and in systemd --user domains. The specifiers will return the pw_name and pw_dir fields if the unit file has a User= field. If the unit file does not have a User= field, the value substituted is either $USER or $HOME from the environment, or, if unset, the values from pw_name or pw_dir. This patch is somewhat after Ran Benita's original patch, which didn't get merged. I've split up the 2 specifiers and extended them to do what is logically expected from these specifiers. Note that expansion is done at `start` time, not after the units are parsed. Using `systemctl show` will just show the specifiers.
