treewide: use mkPackageOption
This commit replaces a lot of usages of `mkOption` with the package
type, to be `mkPackageOption`, in order to reduce the amount of code.

### Implementation ###

# zrepl looks for its config in this location by default. This
# allows the use of e.g. `zrepl signal wakeup <job>` without having
# to specify the storepath of the config.

systemd.packages = [ cfg.package ];
# Note that pkgs.zrepl copies and adapts the upstream systemd unit, and
# the fields defined here only override certain fields from that unit.
