usbconfig: add -l option to dump_device_desc for single line output

Like pciconf -l add a -l to dump_device_desc for usbconfig which will
fold most fields into a single line. We do filter out some we think
will not be interesting in this case.

While mangling with string output in ways not always anticipated when
the program was initially written this should help to parse the
available devices for programs like fwget(8). While I had this in
mind for other bits for a while I got prompted by D48678 to finally
do it.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.
