always trim the newline character from hostname

Description of problem:
On my system /bin/hostname returns a name without a domain name:
$ /bin/hostname
leela

This confuses sosreport, because it expects to find a dot (".") in the returned hostname. The 'hostName' function then returns the name including the newline character, which has funny results:
