Fall back to `dash` on macOS, because `bash` randomly drops serial
input, causing the tool to hang.
Flush the command buffer before sending the requested command. A
failed upload session can cause characters to remain in the command
buffer.
Redirect stdin instead of using a separate file descriptor. Also do
this before running `stty`. This allows the `stty` settings to
actually take effect on macOS, which seems to reset the termios
state of serial devices upon the last close of the device.
Tested on macOS 10.15 and Ubuntu 20.04.

Instead of simply echoing "device.reset" into the device port, call
`bin/focus-send`, which sets the `raw` setting on the port, before writing into
it. Without that, the command is not recognised by the firmware.
We could do the stty call in the makefile directly, but to support macOS, we'd
need to treat that specially, and at that point, it's easier to just call
`bin/focus-send`. The sketch relies on having the Kaleidoscope repo available
anyway, so we can safely rely on `bin/focus-send` being there, too.
Because we're now using the tool in the makefiles, `focus-test` was renamed to
`focus-send`.
