platform_Cryptohome, cryptohome.py: kill c-homed on dbus silence

Move platform_Cryptohome over to using the CryptohomeProxy and
ensure that any unreplied DBus call results in cryptohomed being
ABRT'd with the hope that we'll get a crash dump on daisy flake.

As we discover blocking operations, we can move them off the main
thread.

TEST=passes; kills -ABRT if cryptohomed gets a SIGSTOP during the test (as a proof of hang detection)
