ostree: fix a parallel compilation issue
ostree: fix a parallel compilation issue

A regression was introduced by commit 7a464681:

    ostree: update to 2017.13

    To fix compilation issues, we update to 2017.13 and keep in sync
    with meta-updater's version.

it reverted a following commit 7b436f86:

    ostree: inherit autotools-brokensep instead of autotools

    Autotools class for ostree recipe where separates build dir doesn't
    work well, we have observed quite a few parellel compilation issues, so
    we change it to inherit autotools-brokensep instead, which probably can
    fix those issues, and this is also how autotools is being used in
    ostree recipe of meta-updater project.

this lead ostree fail on parallel compilation again, add it back.
