m/p/watchdog: add watchdog package

This adds the watchdog package for interfacing with devices implementing
the Linux watchdog API. There is one alternative implementation at
github.com/mdlayher/watchdog but it is too minimal for our use case.

The kernel API contains a bunch of weird status bits only relevant for
physical watchdog cards which are not made accessible through the
Go package.

Sadly there are no integration tests for this package as ktest wouldn't
work for this because a) no watchdog HW and b) the test success depends
on a condition outside the kernel.
