Pcbnew, fixed (I hope) a Linux specific issue:

* For an obscure reason the focus is lost after loading a board file when starting Pcbnew
* (i.e. only when launching Pcbnew from Kicad or from a command line, with a board filename to load))
* (seems due to the recreation of the layer manager after loading the file)
* This is more a workaround than a fix.
