[OE-core] [PATCH 1/4] devtool: extract: prevent externalsrc from interfering with extraction

[Paul Eggleton]

In case the user has set up externalsrc outside of devtool, force
EXTERNALSRC to blank for the recipe when extracting so that the original
source URI is still in SRC_URI and we're still able to extract it. (This
isn't a problem with devtool itself because the bbappends within the
workspace layer that apply externalsrc are explicitly filtered out when
devtool parses a recipe).
