Nick Kralevich c3c9052bc7 Make DEFAULT_SYSTEM_DEV_CERTIFICATE available in keys.conf
In 9af6f1bd59, the -d option
was dropped from insertkeys.py. This was done to allow an
Android distribution to replace the default version of
keys.conf distributed in external/sepolicy/keys.conf. keys.conf
was modified to reference the publicly known test keys in
build/target/product/security.

Unfortunately, this broke Google's build of Android. Instead
of incorporating our keys directory, we were using the
default AOSP keys. As a result, apps were getting assigned
to the wrong SELinux domain. (see "Steps to reproduce" below)

This change continues to allow others to replace keys.conf,
but makes DEFAULT_SYSTEM_DEV_CERTIFICATE available as an
environment variable in case the customized version wants to
make reference to it. This change also modifies the stock
version of keys.conf to use DEFAULT_SYSTEM_DEV_CERTIFICATE,
which should be appropriate for most Android distributions.
It doesn't make any sense to force each OEM to have a copy of
this file.

Steps to reproduce.

1) Compile and boot Android.
2) Run the following command: "adb shell ps -Z | grep process.media"

Expected:

  $ adb shell ps -Z | grep process.media
  u:r:media_app:s0               u0_a5     1332  202   android.process.media

Actual:

  $ adb shell ps -Z | grep process.media
  u:r:untrusted_app:s0           u0_a5     3617  187   android.process.media

# Maps an arbitrary tag [TAGNAME] with the string contents found in
# TARGET_BUILD_VARIANT. Common convention is to start TAGNAME with an @ and
# name it after the base file name of the pem file.
#
# Each tag (section) then allows one to specify any string found in
# TARGET_BUILD_VARIANT. Typcially this is user, eng, and userdebug. Another
# option is to use ALL which will match ANY TARGET_BUILD_VARIANT string.
