The 'bootcount' value is now incremented and stored in the system on every boot and
not only then the 'upgrade_available' flag is set. Also, ensure the value is cleared
when the 'altboot' script is executed by running the new U-Boot command 'bootcount reset'.

When Dual Boot is not enabled, 'rootfsvol' variable must point to the
single boot system rootfs partition 'rootfs'.
Explicitly set this value. Otherwise the script relays on the default
rootfsvol value, which may be a Dual Boot partition.
