update_engine: Migrate build system to gyp.
This change migrates the SConstruct file to the platform2 gyp
infrastructure without changing the way UE is compiled. The
code is still compiled as a single static library shared
between delta_generator, update_engine and update_engine_client.
This patch adds two generic .gypi rules to generate bindings for
DBus glib and public keys using openssl.
update_engine_unittests requires to run the openssl version from the
board and not the one on the host. This changes does that by using
SYSROOT when possible.
delta_generator is built without -pie to avoid a bug on how it
is run from au-generator.zip.
