Cygwin: socket files are not lnk special files
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().
