And some more minor fixes and improvements also for the build system.

v2021.08.0: Merge pull request #301 from kurt-vd/canbusload-fd

Tag a new release for Debian Upstream to ship improvements and fixes since v2020.11.0 (2020-11-06):

Support of new kernel features:

• add len8_dlc support for Classical CAN frames (Linux v5.11+)

v2020.12.0

candump: Enable zero relative timestamps to be used in log files

The logfile format which is generated with '-l' and '-L' consists of an
absolute epoch timestamp. In some use cases (e.g. for documentation) a
zero relative timestamp can be useful which was only configurable with
the '-tz' option for the classic output.

'-tz' and '-ta' are now valid options for the logfile format.
