bitbake: lib/bb/siggen: show word-diff for single-line values containing spaces

If a variable value has changed and either the new or old value contains
spaces, a word diff should be appropriate and may be a bit more readable.
Import the "simplediff" module and use it to show a word diff (in the
style of GNU wdiff and git diff --word-diff).

Also use a similar style diff to show changes in the runtaskhashes list.
I didn't use an actual word-diff here since it's a little different - we
can be sure that the list is a list and not simply a free-format string.
