devtool: correctly handle non-standard source tree locations in upgrades

When S is set to a sub-directory of upstream source, the license
checks and the bbappend writing (specifically, setting EXTERNALSRC)
need to operate on that sub-directory.

'devtool modify' already has similar logic, and it was copied from there
and adjusted.
