x86_64: fix invoking sysupgrade on PARTUUID mounted system
Fix sysupgrade to determine the correct boot block device to use if /proc/cmdline contains a PARTUUID root. Change the preinit move_config() hook to use the UUID scanning code from sysupgrade in order to avoid code duplication. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@42968 3c298f89-4303-0410-b956-a3cf2f4a3e73
