Linux: Add abstract address support for QLocal{Socket,Server}

Takes advantage of Linux's and Android's support for abstract namespace
when binding sockets, which is independent of the filesystem (see man
entry for unix domain sockets).

To make QLocalServer and QLocalSocket use an abstract socket address,
one needs to set the socket options to QLocalServer::AbstractNamespaceOption.

Fixes: QTBUG-16090
