core: Switch usbi_transfer to store timeout as timespec

The transfer timeout is structured around time values provided by the
clock_gettime() function. This function uses a timespec structure, but
the usbi_transfer structure was storing its calculated timeout in a
timeval structure. This mismatch introduces extra work when checking for
transfer timeouts as there must be a conversion between these two
structures. Eliminate this by storing the calculated timeout as a
timespec, thus allowing direct comparison.

Note that a conversion to a timeval is still necessary in the
libusb_get_next_timeout() function because the public API uses a timeval
structure, but this is now the only place where such a conversion is
done.

libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD and Haiku userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).

libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems. Please see the PORTING file for more information.
