This change does two things: 1. Fixes inadvertent inheriting of 'crashkernel=' parameter when eos2sonic script is used for converting a device from Eos to SONiC. This makes sure that we are not working with old kdump configuration as constraints on SONiC maybe different from EOS. 2. Adds 'crashkernel=' parameter to cmdline, which enables kdump by default when the system boots up. Signed-off-by: Mohan Yelugoti <ymd@arista.com>

Adds 'crashkernel=' parameter to cmdline, which enables kdump by default when the system boots up.
This removes the need to do additional reboot to get kdump to operationally ready state.

How I did it
How to verify it
SONiC -> SONiC image: On the DUT running SONiC without these changes and having kdump disabled, re-sanitized it with SONiC image containing these changes.
EOS -> SONiC image: Used the eos2sonic script to convert DUT from EOS to SONiC. Verified that it doesn't inherit EOS crashkernel parameters and boots up with default parameters from these changes.
