src.conf: Add a MK_ZFS_TESTS knob

The in-tree ZFS test suite is somewhat outdated and I see a number of
failures there. I tend to think that we want to integrate the OpenZFS
test suite somehow, replacing the legacy one, though it's also possible
to run that as a separate test suite.

In any case, if one wants to run the OpenZFS test suite separately, it's
useful to be able to disable installation of the legacy ZFS test suite,
so let's provide a src.conf option to do that.

loader: Add WITH/WITHOUT_LOADER_PXEBOOT build option

Make it possible to disable pxeboot. This loader will fail to build when
it's too large. When /boot/loader needs to be larger like that, this
options will disable a component whose build will fail. It is an explicit
option rather than implicit when things are too large to force the user to
make the explicit tradeoffs rather than wonder why they have a stale pxeboot
or other odd failure mode.

loader: Document that WITH_BEARSSL may need other tweaks

/boot/loader is right up aginst the 500k limit we have to make sure
everything works in a wide variety of environments. However, adding
WITH_BEARSSL can push it over the edge since we are so close to the
limit with it enabled. One may also need to increase LOADERSIZE when
enabling it. It's often safe to go much higher, especially when you
don't plan on using pxeldr. Document this trade off here.
