Set default audio-output-buffer to 10ms

Browse source 
Change the default value of `--audio-output-buffer` from 5ms to 10ms.

In practice, the audio output backends do not support values below 10ms.
When the setting is set to 5ms, several successive calls are made every
10ms or more.

Additionally, a 5ms output buffer can cause audio glitches on some
computers.

It is also possible to configure another audio buffer (the audio output buffer),
by default set to 5ms. Don't change it, unless you get some [robotic and glitchy
sound][#3793]:
by default set to 10ms. Do not change this setting unless you have a good reason
(see [robotic and glitchy sound][#3793]). For instance:
```bash
# Only if absolutely necessary
scrcpy --audio-output-buffer=10
scrcpy --audio-output-buffer=5
```
