fix(android/pad-audio): pin the uac-host that unmutes the pad

The pad rendered nothing — not its speaker, not its voice coils — because
`uac-host` streamed into a device it never unmuted. It set the sample rate and
nothing else; the UAC Feature Unit, where Mute and Volume live, was parsed by
nobody. Every counter stayed green throughout: URBs completed, 0 short bytes,
0 URB errors, 0 short writes here, decoded peak 19345. None of them can observe
mute, so a muted device is indistinguishable from a working one.

Bumps the pin to unom-io/usbfs-iso f3de1fd, which sends SET_CUR Mute=0 and
Volume=0 dB to the Feature Unit before the stream starts.

With this in, Spider-Man Remastered's haptics reach the physical DualSense
through the virtual pad, confirmed by feel on real hardware.
