Make backend for shared library fuzzing.
Additional context (for Googlers): go/android-fuzzing-shared
This patch adds the Make support for automatically installing sanitized
dependent shared libraries. 'make $module' will find all the shared
library dependencies in soong, and create the rules to install them. We
simply need to add the <install sanitized shared library> rule that's
made by Soong as a dependency of the module's phony.
We also now change 'm fuzz' to not just build the fuzz packages, but to
build all fuzz targets into the respective
$ANDROID_PRODUCT_OUT/data/fuzz and $ANDROID_HOST_OUT/fuzz directories.
Bug: N/A
Test: Build fuzz target with shared libs, note the contents of
$ANDROID_PRODUCT_OUT/data/fuzz/lib and out/soong/fuzz-target-*.zip now
has shared libraries.
