Added if DEBUG_PERMISSIONS statement to "Un-granting permission" log in PermissionManagerServices

Fixes: 131721301

Test: change the DEBUG_PERMISSIONS static field to true, then install an
apk via ADB. Check logcat to verify the log is present. Then set
DEBUG_PERMISSIONS to false, install another apk, and verify the logs are
not present
