base.bbclass: Add LIC_FILES_CHKSUM files to checksum files.
Previously, files with absolute paths in LIC_FILES_CHKSUM such as
"file://${COMMON_LICENSE_DIR}/foo" would not result in a qa failure
when the license file changed.
To fix this problem, add any files with absolute paths from
LIC_FILES_CHKSUM to the file-checksums varflag, so that changes in the
license file are detected and cause the qa task for licenses to run.
