[Arista] Fix boot0 code for docker_inram

Browse Source 
Enable docker_inram for all systems with 4GB or less of flash.
This is mandatory to allow these systems to store 2 SONiC images.

This change also fixes the missing docker_inram attribute when
installing a new image from SONiC.
Because the SWI image can ship with additional kernel parameters within
such as `sonic_fips=` this lead to a conflict.
To prevent the conflict, the extra kernel parameters from the SWI are
now stored in the file `kernel-cmdline-append` which isn't used anywhere.
