[Bug 13971] https://bugzilla.yoctoproject.org/show_bug.cgi?id=13971
A recipe using LICENSE=CLOSED would normally not have LIC_FILES_CHKSUM
set.
If LIC_FILES_CHKSUM was not set, it would cause `devtool upgrade` to fail.
This fixes the issue by defaulting to an empty string if
LIC_FILES_CHKSUM is not found.
