[arista]: Fix convertfs condition for booting from EOS (#4139)

Browse Source 
Fix the issue of incorrectly skipping the convertfs hook when fast-reboot from EOS, by adding an extra kernel cmdline param "prev_os" to differentiate fast-reboot from EOS and from SONiC.

This is because we still do disk conversion for fast reboot from eos to sonic, like format the disk.
