dumpcap: clean up capture device open errors.

1) Consistently say "capture device"; not all capture devices are
"interfaces" in the sense of "network interfaces' ("any" means "all
network interfaces", and capturing may be supported on a USB bus or on
D-Bus or....)

2) Use double quotes to quote the device specifier (it probably won't
have spaces in its name, but...).

3) Make sure that there's a space between "capture device" and the
quoted device name.
