lib/oe/path: Fix tar invocation with --no-recursion

tar's --no-recursion flag only applies to files mentioned after the
flag, which made it a no-op in this invocation of tar, because it was at
the end of the command line.

This is simple to verify with GNU tar 1.29:

| $ mkdir foo
| $ mkdir foo/dir
| $ touch foo/dir/file
| $ tar -cf - foo --no-recursion | tar t
| foo/
| foo/dir/
| foo/dir/file
| $ tar -cf - --no-recursion foo | tar t
| foo/

Modify the code so that it actually does what the comment says by moving
the flag in front of the --files-from argument.
