libsystemd: export sd-netlink

It was added originally in 65f568bbeb9b8c70200e44c19a797df3a0bfd485. The API is
has stabilized pretty much, and generally follows the usual style for
libsystemd.  We've held it as a public-but-private library for almost 10 years,
let's export it.

sd_netlink_sendv() and sd_nfnl_nft_*() are excluded.

libsystemd.so seems to grow by 12k.
