typecd: Rename ectool seccomp policy file

The same ectool seccomp policy file is used by both GetInventory
and EcTypeCEnterMode commands. Change the name to a more generic one to
reflect this.

BUG=b:171725237
TEST=Build and deploy debugd on volteer, and ensure the GetInventory
D-Bus command still succeeds. The command is:
dbus-send --system --dest=org.chromium.debugd --print-reply
/org/chromium/debugd org.chromium.debugd.EcGetInventory
