[OE-core] [PATCH 0/2] Set STAMPCLEAN for externalsrc when S == B

[Ola x Nilsson]

When using devtool modify and changing code back and forth bitbake
sometimes does not realize that a rebuild is required.  This is
because STAMP and STAMPCLEAN doesn't match.  Old stamps confuse
bitbake and when the files in ${S} happen to match something we've
seen before bitbake decides to do nothing.

Fix by setting STAMPCLEAN.
Add tests.

  externalsrc: Set STAMPCLEAN to match STAMP
