[Bug libc/1012] New: gethostid() output sign-extended on 64-bit platforms

["edwardsg at sgi dot com" <sourceware-bugzilla at sources dot redhat dot com>]

There is a signed int to signed long bug in gethostid() for 64-bit
platforms.  If the 31st bit of the hostid is a 1, it gets signed
extended to 64 bits.  It should instead be cast as an unsigned int on
return.  Example:

# hostid
ffffffffa2802df3

With the attached patch, it returns to the expected output:

# hostid
a2802df3
