fix: Add Minimum-free ZRAM configuration

Browse Source 
It assures that this value will get properly configured for systems with ≥6.75GBs of RAM.

As this article shows, too low of a value is not good, and too high of a value is not good.

It is the only remaining non-applied ZRAM tweak from Pop-OS, which they included in their zram service.

pop-os/default-settings@7fcad35#diff-964fc7d24025670fb776c01ef2943c84e637a3675c164696aebae19d86c8d46eR62

This checks if minimum-free ZRAM value is 1% of the maximum RAM of the current system, hence why this must go to the hardware service compared to simple sysctl config change.

# HOSTNAME FIX
# If the hostname is too long Distrobox will fail during setup
# Additonally, Anaconda likes to set the hostname to be the ipv6 address
