Bug 8997: change libreplace GPL source to LGPL

libreplace currently includes socket.c and getifaddrs.c both of which
are GPL licensed.
Although not required, talloc and tdb build alongside this source,
leading to some ambiguity regarding their LGPL licences.

The following copyright holders have agreed to the GPL->LGPL change:
lib/replace/getifaddrs.c

lib/replace/socket.c
