[Unstable][K][PATCH] UBUNTU: [Packaging] Make stamp-install-<flavor> target reentrant

[Juerg Haefliger]

During development or for debugging purposes it's sometimes desirable to
run 'debian/rules build-<flavor>' multiple times in a row without starting
from scratch, i.e. without cleaning the build first. Currently this fails
because make tries to move a subdirectory to an already existing location
when installing files for the modules extra package:

mv: cannot move '/build/debian/linux-modules-5.15.0-1016-oracle/lib/modules/5.15.0-1016-oracle/kernel' to '/build/debian/linux-modules-extra-5.15.0-1016-oracle/lib/modules/5.15.0-1016-oracle/kernel/kernel': Directory not empty
make: *** [debian/rules.d/2-binary-arch.mk:155: /build/debian/stamps/stamp-install-oracle] Error 1

Fix that by properly running dh_prep at the beginning of the install
target.
