Cygwin: gethostname: fix fetching hostname from non-winsock function

Browse Source 
If gethostname() fails we call GetComputerNameEx with
ComputerNameDnsFullyQualified.  This is wrong, gethostname should return
the hostname only, not the FQDN.  Fix this by calling GetComputerNameEx
with ComputerNameDnsHostname.
