Title:
snapcraft.yaml: missing ubuntu-retpoline-extract-one script breaks the
build

Bug description:
Impact:
The Ubuntu kernel source code depends on the presence of the
retpoline-extract-one file in the script directory during build (see
scripts/Makefile.build::cmd_ubuntu_retpoline) - such a file lives in the
debian directory and is copied to scripts during the 'debian/rules clean' phase.
Snapcraft is oblivious to the debian details, and the clean target is
never invoked, breaking the normal kernel build (make defconfig; make
...).
Check out the Xenia/generic or Bionic/generic tree, cd into it and
execute: make defconfig && make or snapcraft.

Verify that the part is using the correct parameters and try again.
Fix:
To workaround that, before starting the build, make snapcraft do the
copy and fix the build.
Regression risk:
The patch only modifies snapcraft.yaml, so none.
