fix: use exec in launchd daemon config

fix: dont use a script thats in the nix store

fix: remove manual wait4path in linux-builder

fix: remove manual wait4path in karabiner elements

fix: remove manual wait4path in nix-daemon

fix: remove manual wait4path in nix-optimise

fix: remove manual wait4path in tailscaled

fix: autossh test

Revert "fix: remove manual wait4path in nix-daemon"

This reverts commit 6aec084fa5.

fix: remove bad exec

Reapply "fix: remove manual wait4path in nix-daemon"

This reverts commit c8f136ecc5.

fix: update autossh test

to reflect changes in f86e6133d9

fix: services-activate-system-changed-label-prefix test

fix: services-buildkite-agent test

fix: services-activate-system test

fix: escape ampersand

fix: services-lorri test

fix: services-nix-optimise test

refactor: use script rather than command in daemon

fix: use config.command for clarity

style: fix indentation

fix: use lib.getExe rather than directly pointing to file

- mistaken refactor meant that service waited for nix store and not the relevant path

This option implements `Override local DNS` as it is not yet implemented in Tailscaled-on-macOS.
To use this option, in the Tailscale control panel:
1. at least one DNS server is added
2. `Override local DNS` is enabled
As this option sets 100.100.100.100 as your sole DNS server, if the requirements above are not met,
all non-MagicDNS queries WILL fail.

DNS servers should be configured on the Tailscale control panel when `services.tailscale.overrideLocalDns` is enabled.
A race condition can occur when DNS servers are set locally, leading to MagicDNS to not work.
