backports: add __pskb_copy_fclone()

__pskb_copy() was renamed to __pskb_copy_fclone() in most places and
got an extra parameter, it should be safe to just ignore this extra
parameter.

backports: Revert "remove parameter from dma_buf_export()"

The linux commit which made backports need this patch was removed from
linux-next.

This reverts commit 6e1b080e83f1537d8d198917180d0a8bdfd7e0c9.

backports: do not include net_ieee802154_lowpan in kernel >= 3.16

In kernel >= 3.16 this backport is not needed at all. When
CPTCFG_IEEE802154_6LOWPAN is not set it should not get build, we do not
have to check if we are kernel > 3.5, because in an other case
ieee802.15.4 will not get build. Kernel version 3.15 needs a different
backport than the older versions.
