Fix: deps to sanitizer runtime libs are with correct 'image' variant

This change fixes a bug that sanitizer runtime libs for non-core variant
(e.g. recovery, vendor, etc.) are not installed. It happened because the
dependency to the sanitizer runtime lib was without 'image' variant,
which in most case caused only the core variant - which is the first in
the image variants - of the lib to be installed.

Fixing the issue by correctly selecting image variant depending on the
location of the lib having dependency to the runtime lib.
