Subject: pybridge: Stop hard-coding endian flag in DBusChannel

When you issue sd_bus_read() you'll always get the data returned to in
the machines native endianness. Therefore the endianness flag can be set
based on the machines architecture.

This is apparently "undertested" on systemd's end so this may have to
fixed in the future if we run into real world cases where sd_bus_read()
doesn't return data in native endianness.
