[hipcc] fix hipconfig -n behavior

The '-n' hipconfig option now prints a newline, instead of
printing the full output followed by a newline.

This allows us to run something like 'hipconfig -p -n', which will
print the path followed by a newline, instead of the path, the full
output, and then a newline.

The previous 'hipconfig -n' behavior can still be replicated with
'hipconfig -f -n'
