kmod: remove snd_seq_dummy and snd_hrtimer

[redzynix]

snd_seq_dummy and snd_hrtimer are present while pipewire is enabled in ubuntu 24.04.
Those modules prevent snd_seq and snd_timer from unloading and sof_remove.sh fails.

Failed logs from old version, these errors are not present with this commit applied.

[marc-hb]

I see nothing wrong with the small code change but I don't understand the explanation and commit message.

Are these (new?) kernel modules? So how does it affect Ubuntu 24 only? SOF developers are expected to test new kernel versions on any distribution they use.

Or did you mean something like: "The pulseaudio and/or pipewire version and/or configuration in Ubuntu 24 indirectly loads two additional modules"?

I'm confused sorry.

[kv2019i]

Seems good.

@marc-hb Newer Pipewire versions load these modules under some conditions. Given these are old modules and user could load these via other means as well (and block sof_remove.sh), I think this is useful addition in any case.
