062: Sort recursive getfattr output

Test 062 was made "generic" a while back, but it fails on any filesystem
which returns getfattr -R results (aka readdir results) in something
other than inode-order.

With a little awk-fu we can sort the records from getfattr -R so that
the output is the same for xfs as well as ext4, etc.

Also filter out lost+found which extN creates at mkfs time, but
some other filesystems do not.
