[wifi] capture: OpenBSD support
...
Filter the tcpdump output on "received by filter" instead of "captured",
since the OpenBSD's tcpdump does not print the number of packets
captured.

[wifi] capture: fix invoke_tcpdump()
...
When the number of packets captured was >0, set -e stopped the program
as invoke_tcpdump() returned a non-zero value. This is fixed by using
echo instead of return.
Some messages improved, too.

[wifi] capture: fix channel setting on Linux
...
On Linux, at least with the rt2500pci driver, the interface must be down
to set the mode, but up (and in managed mode) to set the channel.

[wifi] capture: fix channel setting
...
At least on NetBSD with the ath driver, it is impossible to change the
channel when the interface is in monitor mode (actually it is possible,
but when the interface is turned up again the channel is set back to its
prior value).
Therefore, to set the interface in monitor mode on a given channel, we
must:
- shut down,
- switch to managed mode (media autoselect) with the wanted channel,
- turn up,
- shut down again,
- switch to monitor mode,
- turn up again.
I implemented the same behaviour for Linux, maybe it's useless but it
can't hurt.
