[OE-core] [PATCH] insane, license: Trap MalformedUrl exceptions when parsing LIC_FILES_CHKSUM

[Phil Blundell]

bb.fetch.decodeurl() will throw if it doesn't like the look of the URL that
it's given.  (Bitbake's idea of what constitutes a valid URL is somewhat
idiosyncratic so it is fairly easy to trip over this by mistake when writing
a recipe.)

If these exceptions are allowed to propagate all the way up to better_exec()
then we will get a large amount of python stack trace spew when they are
finally caught.  Avoid that by catching them locally and throwing
bb.build.FuncFailed() with a suitable explanation instead.
