Fix agama-client not working

[romankuchin]

Just spaces around {} were missing. Typo.

You can't remove space from content:

root@romankuchin-2:~# H=$(hostname)
root@romankuchin-2:~# echo ${H}
romankuchin-2
root@romankuchin-2:~# echo ${H: -3}  <--- space is required to get last 3 chars  
n-2
root@romankuchin-2:~# echo ${H:-3}
romankuchin-2

Ok, thank you for fixing it anyway, just ran it and tested, can confirm it's now working! 💯
