poweralertd: fix regression
This fixes a regression introduced in
8d7e352a4b. That commit made the false
assumption that utils would have propagated from Nixpkgs to Home
Manager. This commit copies in `escapeSystemdExecArgs` to fix the
immediate issue, perhaps we can pull this in some other way later down
the line.
