cygprofile: Manifest changes for isolated processes necessary for O.

Starting from Android O it is no longer possible to run any of the
processes isolated. However, it is not necessary if SELinux is in
permissive mode, which the orderfile generator sets (see
tools/cygprofile/profile_android_startup.py in _SetUpDevice).

This CL therefore removes the orderfile-specific changes to the android
manifest for all builds.
