[Libguestfs] [PATCH v2] test-data: Allow tests to be run when Btrfs is not available.

[Richard W.M. Jones]

v2:

 - Moved the btrfs available test into the subclause where it is used.

Note I got tired of fighting emacs indentation mode and I pushed a
whitespace only patch which fixes the indentation to be 4 spaces
instead of 2 spaces:

This v2 patch requires that one.

Rich.
