Work around QLocalSocket::error deprecation

Centralizing does not bring much benefit here, it's just six locations,
and having either a central #include <QLocalSocket> in algorithm.h
or a separe file does not sound better.

In any case, it is absurd, that deprecating functions to "make code
nicer" requires spilling #if QT_VERSION_CHECK over the code.
