[PATCH 3/3] isar-bootstrap: Avoid absolute paths in SRC_URI

[Uladzimir Bely <ubely@ilbers.de>]

After commit ae3c091c, absolute path to source list file appears in
SRC_URI for isar-bootstrap tasks.

This leads to broken SSTATE_DIR sharing between different instances of
isar on the same machine, since almost all tasks depend on bootstrap
one.

This patch fixes the issue by leaving relative paths returned by
get_aptsources_list() function.
