fixture: Add missing trailing NUL in security.selinux xattr
Because we were only doing bare-user checkouts in the test
suite (and not trying to physically materialize the xattrs)
and because ostree today doesn't validate xattrs, this
problem was silently ignored. But I was looking at
changing the tests to do a checkout, and this caused confusing
failures.
Add the missing trailing NUL. Also while we're here,
split the xattr function in two; one which returns the
Rust-native value and a wrapper which converts to GVariant.

tests: Add some error context
This helped me debug a recent problem.
