Stage "libasound2t64" instead of the virtual package "libasound2" (BugFix)

[LiaoU3]

Description

libasound2 is not a virtual package before noble (e.g. jammy), but it is in noble. Moreover, it seems like in the build for arm64 (currently it only happened on arm64 and if you search for "asound", you will find that it installed both packages on arm), snapcraft tried to package both libasound2t64 and liboss4-salsa-asound2, which should no happened (I will create a bug for snapcraft). Since these 2 packages conflict each other, and actually what we want is libasound2t64.

Overall, I not only to try to workaround the snapcraft issue, but also think it is better to point out the package we want.

$ sudo apt install libasound2

Package libasound2 is a virtual package provided by:
  libasound2t64 1.2.11-1ubuntu0.1 (= 1.2.11-1ubuntu0.1)
  liboss4-salsa-asound2 4.2-build2020-1ubuntu3
You should explicitly select one to install.

E: Package 'libasound2' has no installation candidate

I build a checkbox24 with replacing libasound2 with libasound2t64

Before

ubuntu@ubuntu:~$ checkbox.shell 
checkbox runtime shell, type 'exit' to quit the session
(checkbox-shell) ubuntu@ubuntu:~$ amixer 
amixer: error while loading shared libraries: libOSSlib.so: cannot open shared object file: No such file or directory

After

ubuntu@ubuntu:~$ checkbox.shell

I create canonical/snapcraft#5621 to track the snapcraft issue I mentioned above.
