devtool/upgrade: fix the order of license checksum representation

devtool/upgrade: fix the order of license checksum representation

In most recipes in OE, beginline and endline are before md5 checksum.
We should obey this tradition in devtool's upgrade. Otherwise, we might
see meaningless change just because of the order change.

e.g.
-LIC_FILES_CHKSUM = "file://doc/LICENSE;md5=7765a3d787cb4fed3ccc3c9cee030af9 \
