this works:
```fish
> distrobox-host-exec podman version
Client: Podman Engine
Version: 4.2.0
API Version: 4.2.0
Go Version: go1.18.4
Built: Thu Aug 11 22:42:17 2022
OS/Arch: linux/amd64
```
this doesn't:
```fish
> distrobox-host-exec "podman version"
Failed to start command: Failed to execute child process “podman version” (No such file or directory)
```
Executing commands on the host, while inside of a container, can be done
either with flatpak-spawn, of playing tricks with chroot. Let's provide
a new script, which will be available inside of the container, that does
exactly that.
This tries to improve (although maybe not completely fix):
