linux: Don't set VTIME in UART configuration for esptun
...
`read(esp_fd)` should wait for 1 or more characters to be available in
the UART FIFO, no timing required.

linux: Simplify esptun by getting rid of some helper functions
...
`cread` and `cwrite` are trivial and only called in one place, so just
integrate them.

linux: Set timeout argument on poll() properly
...
`0` for the timeout means *return immediately* instead of
*wait forever*. This is absolutely unnecessary, so change
the argument to `-1` which does mean *wait until something happens*.

linux: Solve an issue with incomplete packets
...
esp_read_responses was throwing away the buffer contents between
invocations, which is not a good idea if there might be a (partial)
async notification such a a received packet in there.

The maximum baudrate seems unstable at times, tune it down a bit.

linux: deduplicate esp receive logic in esptun
...
Unify the two similar serial receive loops.
(as a bonus we'll no longer lose packets that come in through the ESP during
esp_tx_packet)
