[PATCH 23/58] Mark internal netlink functions with attribute_hidden [BZ #18822]

[H.J. Lu]

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.
