Subject: [PATCH] core/unit: fix unit_add_target_dependencies() for units with
 no dependencies

For units without any dependencies, r needs to be initialized to 0.
Otherwise, the return value of unit_add_target_dependencies() is
unspecified.

Conflicts:
	src/core/unit.c

(cherry-picked from db57f3c6d11864f4227bb6734a0d509695a32a7d)

Resolves: #1147524
