the code we used to have in libusb_util.c has been migrated to
libosmousb, a new part of libosmocore.git. Let's remove our historic
copy and use the new shared library instead.

The printing was always only done at the end of osmo_apdu_segment_in(),
so let's leave the decision up to the user if he wants to print the
state at every iteration or not.
We now provide osmo_apdu_dump_context_buf() to the user so he can obtain
a string representation of the internal state for logging at any time he
requires.
