[Stable-9.2.1 08/41] meson.build: Disallow libnfs v6 to fix the broken macOS build

[Michael Tokarev]

From: Thomas Huth <thuth@redhat.com>

The macOS builds in our CI (and possibly other very recent distros)
are currently broken since the update to libnfs version 6 there.
That version apparently comes with a big API breakage. v5.0.3 was
the final release of the old API (see the libnfs commit here:
https://github.com/sahlberg/libnfs/commit/4379837 ).

Disallow version 6.x for now to get the broken CI job working
again. Once somebody had enough time to adapt our code in
block/nfs.c, we can revert this change again.
