[PATCH 3/6] lib/oe/path.py: Align with OE-core regarding sparseness preservation

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

This imports the changes of the OE-core commit
055402e5504f041c346571e243c7cf0894955cad
("sstate/lib.oe.path: Ensure file sparseness is preserved")

Other changes to this file just add functionality that we do not use.
