Dex2oat needs the ability to read from already open file descriptors
in /oem so that apps from that location can be installed. Allow it.

Addresses the following denials:

  avc: denied { read } for comm="dex2oat" path="/oem/app/TabletInfo.apk" dev="mmcblk0p12" ino=20 scontext=u:r:dex2oat:s0 tcontext=u:object_r:oemfs:s0 tclass=file permissive=0

* zygote needs to be able to symlink from dalvik cache to system
  to avoid having to copy boot.oat
  (when the boot.oat file was built with --compile-pic)
* dex2oat needs to be able to read the symlink in the dalvik cache
  (the one that zygote creates)

dex2oat fails when upgrading unlabeled asec containers.

Steps to reproduce:

1) Install a forward locked app on Android 4.1
  adb install -l foo.apk
2) Upgrade to tip-of-tree

Addresses the following denial:

dex2oat can't access file descriptors associated with asec_apk_files.
This breaks installing forward locked apps, and generates the following
denial:

  type=1400 audit(0.0:18): avc: denied { read } for path="/mnt/asec/com.example.android.simplejni-1/pkg.apk" dev="dm-0" ino=12 scontext=u:r:dex2oat:s0 tcontext=u:object_r:asec_apk_file:s0 tclass=file

Steps to reproduce:

  $ adb install -r -l SimpleJNI.apk

Expected:

  app installs

Actual:

  app fails to install.

Currently, dex2oat runs in the installd sandbox, and has
all the SELinux capabilities that installd does. That's too
excessive.

dex2oat handles untrusted user data, so we want to put it in
it's own tighter sandbox.
