package/linux-tools: add USB tools (testusb and ffs-test)

Browse Source 
Extend the linux-tools package to also build the userspace USB tools,
which currently include testusb and ffs-test.

These tools are in the kernel tree since a long time, and althogh a
Makefile had been present since kernel 2.6.39, it has been entirely
rewritten (with an install rule) back with kernel 5.9, to allow building
the same way as other tools provided with the kernel.

We make use of the Makefile install rule, thus version >= 5.9 is
required. Support for older kernels may be added later if needed, and
is left as an exercise for the motivated party.
