Strip device name from gen_notice license files
The output libcore-library-notices gen_notice module is embedded in
core-module-lib-stubs, which is a transtiive dependency of effectively
every javac invocation targeting the device. The output files listed
in the notice file can contain a path that includes the device name,
for example "target/product/generic_arm64/system/framework/core-libart.jar".
This causes the stubs contents to be different for every product,
which drastically reduces the cache hit rate of RBE. Strip the
"out/target/product/generic_arm64" prefix from paths in the notice
file.

Test: unzip -p out/soong/.intermediates/libcore/art.module.public.api.stubs.module_lib/android_common/turbine-combined/art.module.public.api.stubs.module_lib.jar NOTICES/libcore-NOTICES.txt
