Change path_conv::is_lnk_special() so that it returns false on socket files. is_lnk_special() is called by rename2() in order to deal with special files (FIFOs and symlinks, for example) whose Win32 names usually have a ".lnk" suffix. Socket files do not fall into this category, and this change prevents ".lnk" from being appended erroneously when such files are renamed. Remove a now redundant !pc.issocket() from fhandler_disk_file::link().
