jade faf00ad022 libexpr: significantly improve error messages for bad attr paths
This commit makes Lix include the summarized content of the value being
indexed when it is bad.

lix/lix2 » nix eval --expr '{x.y = 2;}' 'x.y.z'
error: the value being indexed in the selection path 'x.y.z' at 'x.y' should be a set but is an integer: 2

lix/lix2 » nix eval --expr '{x.y = { a = 3; };}' 'x.y.z'
error: attribute 'z' in selection path 'x.y.z' not found inside path 'x.y', whose contents are: { a = 3; }
       Did you mean a?

lix/lix2 » nix eval --expr '{x.y = { a = 3; };}' 'x.y.1'
error: the expression selected by the selection path 'x.y.1' should be a list but is a set: { a = 3; }
