Simon Richter 813d876d02 Fix build on GNU Hurd 
Hurd has /proc/self/exe like Linux, so the same mechanism as for Linux
works here.

Because Hurd does not have a path length limit, PATH_MAX is not defined.

Technically, we'd have to allocate a buffer, check whether the returned
size is greater or equal to the buffer size (so the path was truncated),
and then retry with a larger buffer to handle excessively long paths on
Hurd, but in practice there is no NixOS on Hurd and the path is only used
to find Himbächel chipdb files in the absence of an explicit setting, so we
should be safe in assuming the path name will be less than 4kB.

Many thanks to Lofty for doing most of the research here.
