Libguestfs - Jun 2020 - [PATCH nbdkit] build: Rename configure --without-linuxdisk -> --disable-linuxdisk

When I was reviewing this I forgot the slightly ridiculous rules that
autoconf uses for --enable/disable vs --with/without:

https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Package-Options.html
https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/External-Software.html

Since this is disabling an intrinsic feature of the software (a
plugin) it should use --disable.

Updates: commit 2a3efc5836df3d55d304cc4b3ea2800b5e93831a

 dnl or it's too old to support the -d option (eg. on RHEL 7).
