William Roberts 9af6f1bd59 Drop -d option on insertkeys.py in Android.mk
This breaks the ability for users to have certs in many
directories. Currently the design is to allow keys.conf
to specify arbitrary locations for pem files, relative to
the root of the Android tree. If users want to have a
common prefix on all the keys, then they can export
DEFAULT_SYSTEM_DEV_CERTIFICATE, and make that an environment
variable in their keys.conf file.
