create_inode: handle source symlinks with extended attributes

We need to use lgetxattr(2) instead of getxattr(2) or attempts to
create file systems with extended attributes will fail:

set_inode_xattr: No data available while reading attribute "trusted.link" of "link"
__populate_fs: No data available while setting xattrs for "link"
mke2fs: No data available while populating file system
