    Fix kickstarts patching

    Ostree doesn't manage the /var filesystem. Anything
    installed there during initial filesystem setup becomes
    unpatchable [1]. As a result, the kickstart install dir
    /var/www/pages/feed/rel-${platform_release}/kickstart
    is not updated according to patch changes.

    This commit changes the platform-kickstarts install paths
    to a place that ostree handles,
    /usr/share/platform-kickstarts/rel-${platform_release}
    in this case and symlinks it to
    /var/www/pages/feed/rel-${platform_release}/kickstarts.

    Test Plan:
    1. PASS: ISO install and verify symlink created:
             /var/www/pages/feed/rel-${platform_release}/kickstarts ->
             /usr/share/platform-kickstarts/rel-${platform_release}
    2. PASS: Verify that the centos/ dir, kickstart.cfg & miniboot.cfg
             are installed to /usr/share/platform-kickstarts/
             rel-${platform_release}
    3. PASS: Verify PATCH apply, ensure that changes are applied to
             /var/www/pages/feed/rel-${platform_release}/kickstarts
    4. PASS: Manually remove/re-install the platform-kickstarts package
             and verify kickstarts dir and symlink
