Alan Stokes 890414725f Audit execution of app_data_file native code.
On debug builds, introduce audit logging of apps targeting SDK <= 28
that execute native code from a non-priv app home directory via
execve() or dl_open().

Bug: 111338677
Test: Builds + boots.
Test: Launch app that uses private .so files, see granted logs.

### Untrusted_27.

### This file defines the rules for untrusted apps running with
### 25 < targetSdkVersion <= 28.
###
### This file defines the rules for untrusted apps.
### Apps are labeled based on mac_permissions.xml (maps signer and
### optionally package name to seinfo value) and seapp_contexts (maps UID
### and optionally seinfo value to domain for process and type for data
### directory). The untrusted_app_27 domain is the default assignment in
### seapp_contexts for any app with UID between APP_AID (10000)
### and AID_ISOLATED_START (99000) if the app has no specific seinfo
### value as determined from mac_permissions.xml. In current AOSP, this
### domain is assigned to all non-system apps as well as to any system apps
### that are not signed by the platform key. To move
### a system app into a specific domain, add a signer entry for it to
### mac_permissions.xml and assign it one of the pre-existing seinfo values
### or define and use a new seinfo value in both mac_permissions.xml and
### seapp_contexts.
