Zygote: Additional whitelisting for legacy devices.
On M and below, we provide a blanket whitelist for all files under
"/vendor/zygote_whitelist". This path is whitelisted purely to allow
this patch to be applied easily on legacy devices and configurations.
Note that this does not amount to a loosening of our security policy
because whitelisted files are reopened anyway.
Bug: 32691930
Test: manual
