Every file on Solaris 11 and on has two extended attributes, so if we find
them, we shouldn't fail.  Also, we don't support extended attributes on
symlinks, so just quietly pass that test.

Additionally, fix comparison of lists to dict_keys in Python 3. This has been
fixed in newer versions of xattr which will be part of a future update of the
userland version of xattr.

Merged as of 0.7.6.
