This helps avoid issues with nbd not being ready when
we need it.
Still keep various "modprobe nbd" in different test
files - this ensures these test files can still be
run in isolation. But remove the various "rmmod nbd"
to ensure that nbd always stays loaded. There is no
harm in just keeping nbd loaded all the time.

too.
These changes are needed for some upcoming patches which will
apply --whole-archive to all libraries linked into the application.
That patch will require that we never include the same library

Shared library builds *require* that blobfs be listed before
blob on the link line, hence adding blobfs here even though it's
not technically associated with a bdev module.
We can also simplify spdk.modules.mk while we're here - just
filter out bdev_lvol to disable lvol for applications like
blob_cli that need to disable it.
