Cygwin: socket files are not lnk special files

Browse Source 
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().
