Libguestfs - Nov 2018 - [PATCH] tests: Fix shebang tests on FreeBSD.

On FreeBSD we cannot go through the shell script (./nbdkit).  Instead
replace the path with a direct link to both the nbdkit binary and
locally compiled plugin.

Note this does not go through valgrinding when you run
‘make check-valgrind’ so that needs to be fixed at some point in the
future.

Thanks: François Revol and Eric Blake.
