Fix unzip timestamps

ninja: Missing `restat`? An output file is older than the most recent input:
 output: out/target/common/obj/PACKAGING/framework-doc-stubs-metadata_intermediates/activity_actions.txt
  input: out/target/common/obj/PACKAGING/framework-doc-stubs-metadata.zip
ninja: Missing `restat`? An output file is older than the most recent input:
 output: out/target/common/obj/PACKAGING/framework-doc-stubs-metadata_intermediates/broadcast_actions.txt
  input: out/target/common/obj/PACKAGING/framework-doc-stubs-metadata.zip
ninja: Missing `restat`? An output file is older than the most recent input:

ninja: Missing `restat`? An output file is older than the most recent input:

ninja: Missing `restat`? An output file is older than the most recent input:
 output: out/target/common/obj/PACKAGING/framework-doc-stubs-metadata_intermediates/widgets.txt
  input: out/target/common/obj/PACKAGING/framework-doc-stubs-metadata.zip

Which was caused by unzip setting the timestamps of the output files to 2008.

Test: m out/target/common/obj/PACKAGING/framework-doc-stubs-metadata_intermediates/activity_actions.txt
