build: revert moving unstable symbols from libnl_3 linker section

In the past, libnl3 had only one section (libnl_3) in the
linker version script. Between 3.2.25 and 3.2.26 release,
this was cleaned up and new symbols were added to libnl_3_2_26
section. Commit d2a30fb also moved new symbols since 3.2.25
to that section.

Fedora 21 and later already uses these symbols in the previous
version (@libnl_3). Updating there would break symbol lookup.

As we have users of the unstable version from pre-3.2.26, move
those symbols back. Note that this now breaks unstable users since
d2a30fb (5 weeks ago) -- which probably are much fewer affected
users.

Fixes: d2a30fbb36d668fe64f43bddfc9c53ee0362334f
