[OE-core] [PATCH 02/11] classes/insane: improve LIC_FILES_CHKSUM messages

[Paul Eggleton]

* If the md5 parameter is specified with no value, report that the
  checksum is not specified instead of reporting that it has changed
* If the md5 checksum has changed, point directly to the license file in
  a way that is easy to copy and paste and give the line numbers in an
  easy to read form, as well as asking the user to verify that the new
  contents matches the current LICENSE value.
