Don't put "get_home_dir()" inside #ifdef HAVE_LIBPCAP/#endif.

On UNIX, if "$HOME" isn't set, try getting the user ID and the password
entry for that user ID, and, if that succeeds, get the home directory
from the password entry, otherwise use "/tmp".  On NT, it may be
possible to do something similar (get the user name, and append that to
"C:\winnt\profiles\"); I'm not sure whether there's anything that can be
done on Windows 9x.
