Userland: Enhance jail-attach utility to support existing and new jails

Browse source

index as a result, so it was just a matter of using it when calling the
LibCore join_jail function to use the new jail.

`jail-attach` attaches a new process by specifying a command, to an existing jail, with a
specified jail index.
## Options
* `-i`, `--jail-index`: Use an already existing jail with its index
* `-n`, `--jail-name`: Create a new jail with a provided name
## Examples
```sh
# Attach the command "ps -ef" to a jail with the index 0
$ jail-attach 0 ps -ef
# Attach the command "ps -ef" to an already existing jail with the index 0
$ jail-attach -i 0 ps -ef
```
```sh
# Attach the command "/bin/Shell" to a new jail with the name "test jail"
$ jail-attach -n "test jail" /bin/Shell
```
