Debian kFreeBSD support

Regarding #12 This works -ish. 003-load.t fails for me sometimes, I think due to a race condition:

t/003-load.t .......... 1/9 
#   Failed test at t/003-load.t line 20.
#          got: '0.08'
#     expected: '0.07'
# Looks like you failed 1 test of 9.
t/003-load.t .......... Dubious, test returned 1 (wstat 256, 0x100)

On my Debian kFreeBSD box you can also use the Linux driver, as the /proc file system is installed. I am not sure if you can count on /proc being available, however. Curiously using the Linux interface does not seem to suffer this race condition as often.

Yes, there's some amount of raciness involved in that test, which I think I have another pull request sitting around to address.

To set expectations, though... I haven't really touched this code much in several years, so I don't really have a dev environment set up anymore to test, or build releases with. I appreciate the contribution, but I probably won't be able to give it too much attention for a few months (Real Life, etc).

I also don't have much direct use of this module anymore, or much involvement with Perl in general...

If you want to "volunteer" to take up maintainership of this on CPAN and such, I probably wouldn't object.

I think this also needs an update to the use Devel::AssertOS line?

For example, see:

I did not need to update Devel::AssertOS, not sure why.
