[device/arista]: Update (#2336)

* Update arista drivers submodule

* Ignore the possible timestamp warning in tar extraction

* Add verbosity toggle to boot0

Console logging is slow because of the 9600 baud rate.
Some time can be saved by decreasing the console verbosity.

* Add hook mechanism in boot0.

Support additional features in boot0 via hooks.
Hooks are unpacked and executed at post-install or pre-exec time.

* Fix 7170 sensors.conf file

Fix critical temperature settings for MAX6658 sensors

* Fix the random swap of storage devices

For arista 7050 switches running with linux 4.9, it is likely the device
name of flash drive (/dev/sda) and usb (/dev/sdb) randomly swap in kernel
booting, depending on which one is ready first. It breaks the expectation
that flash will be mounted as root by setting root=/dev/sda1. This patch
will correct ROOT to flash device refering to the path under block_flash.

* Fix 7170 fancontrol

* Do not remove aquota.user file in boot0

This file is a filesystem protected file used by EOS.
It can be simply removed and will make the SONiC installation failed if
not skipped.
