Mark internal netlink functions with attribute_hidden to allow direct
access within libc.so and libc.a without using GOT nor PLT.
[BZ #18822]
* sysdeps/unix/sysv/linux/netlinkaccess.h (__netlink_open): Add
attribute_hidden.
(__netlink_close): Likewise.
(__netlink_free_handle): Likewise.
(__netlink_request): Likewise.
