The profile script previously nuked `XDG_DATA_DIRS` and then
“helpfully” re-populated it with FHS paths. This was especially
bad for systems like NixOS, which do not have `/usr`
and rely on `XDG_DATA_DIRS` heavily.
Quoting from https://fishshell.com/docs/current/cmds/set.html
> If a variable is set to zero elements, it will become a list with zero elements.
And indeed, that is what the `set -x --path XDG_DATA_DIRS` command does.
We need to list the value explicitly, if we want to preserve it
while setting variable options.
