[Libguestfs] LIBGUESTFS_PATH is broken in Fedora Rawhide

[Richard W.M. Jones]

$ libguestfs-test-tool
...
libguestfs: launch: version=1.42.0fedora=33,release=5.fc33,libvirt
...
libguestfs: build appliance
libguestfs: error: cannot find any suitable libguestfs supermin, fixed or old-style appliance on LIBGUESTFS_PATH (search path: /usr/lib/guestfs)
...

It appears that this configure test is now failing:

... but at the moment I do not understand why.

Rich.
