perf trace beautify ioctl: Beautify sound ioctl's 'cmd' arg

This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.

This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.

E.g.:

  # perf trace -p 22084 -e ioctl 2>&1 | head -5
     0.000 ( 0.068 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0
     0.344 ( 0.041 ms): alsa-sink-ALC3/22084 ioctl(fd: 46</dev/snd/controlC1>, cmd: SNDRV_CTL_ELEM_READ, arg: 0x7fe764018ee0) = 0
     0.403 ( 0.011 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0
     0.427 ( 0.009 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_STATUS_EXT, arg: 0x7fe76c2e0b30) = 0
     2.461 ( 0.042 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0
