octeon: determine sysupgrade-* directory for upgrade automatically

So far, the sysupgrade-* folder used during upgrade in octeon was
hardcoded to contain the board name. Therefore, changing board name
or BOARD_NAME variable in image/Makefile might have broken upgrade.

Improve this by adding a step to determine the folder name via
a wildcard, as it is done for generic nand_upgrade_tar() in
lib/upgrade/nand.sh.

While this still does not remove the problem for existing devices
(which still have the old script), it will entirely remove the
issue on newly added devices on this platform.
