[Libguestfs] [nbdkit PATCH] linuxdisk: Reduce size of test

[Eric Blake]

Using all of ../plugins as the contents for the linuxdisk gets
progressively bigger over time with incremental builds.  Before I
cleaned it up, my plugins/rust/target/debug had accumulated over 6G of
cruft, causing test-linuxdisk-copy-out.sh to fail due to ENOSPC during
mke2fs.  Pick a smaller directory tree to export, but still test that
we expose a subdirectory.

Fixes: 5da0f2fc9 ("Add linuxdisk plugin.")
