This is useful for development where overwriting files out side
the configured prefix will affect the host as well as stateless
systems such as NixOS that don't let packages install to /etc but handle
configuration on their own.

tested with:
$ mkdir inst build && cd build
$ meson \
-Dcreate-log-dirs=false \
-Dsysvrcnd-path=$(realpath ../inst)/etc/rc.d \
-Dsysvinit-path=$(realpath ../inst)/etc/init.d \
-Drootprefix=$(realpath ../inst) \
-Dinstall-sysconfdir=false \
--prefix=$(realpath ../inst) ..
$ ninja install
":" is prettier, but meson 0.56+ doesn't like it:
src/systemd/meson.build:73: DEPRECATION: ":" is not allowed in test name "cc-sd-bus.h:c", it has been replaced with "_"
src/systemd/meson.build:73: DEPRECATION: ":" is not allowed in test name "cc-sd-bus.h:c-ansi", it has been replaced with "_"

Fixes#17568.
With the grandparent change to move most units to app.slice,
those units would be ordered After=app.slice which doesn't make any sense.
Actually they appear earlier, before the manager is even started, and
conceputally it doesn't seem useful to put them under any slice.
... when called with a valid environment variable name. This means that
any time we call it with a fixed string, it is guaranteed to return 0.
(Also when the variable is not present in the environment block.)
Coverity in CID#1435966 was complaining that s->enabled is not "restored" in
all cases. But the code was actually correct, since it should only be
"restored" in the error paths. But let's still make this prettier by not setting
the state before all operations that may fail are done.
We need to set .enabled for the prioq reshuffling operations, so move those down.
No functional change intended.
I tested this on my ZBook Studio G5. I'm not sure if this works for other ZBook studio machines.
I have two more notes on this PR:
- some keys send multiple scancodes. I matched only on one of them, because I couldn't figure out how to match
on all of them. This results in the others still being visible:

I wanted to set the display key to switchvideomode, but another key is already set to that, so I set it to displaytoggle instead.
