[libsndfile] Adjust depenedncies to libsndfile

[daschuer]

that only the really required additional external libraries are needed.

• What does your PR fix?

This fixes link failures in the target project, because libsndfile has more dependencies by default since #23800

• Which triplets are supported/not supported? Have you updated the CI baseline?

No change

• Does your PR follow the maintainer guide?

  Yes

• If you have added/updated a port: Have you run ./vcpkg x-add-version --all and committed the result?

Thanks for making dependencies more accurate!

Unfortunately this PR works only half way:

Installing vamp-sdk only still pulls in the default libsndfile with all dependency along with the waste of CPU time.

./vcpkg install vamp-sdk --dry-run
Computing installation plan...
The following packages will be built and installed:
  * libflac[core]:x64-linux -> 1.3.4
  * libogg[core]:x64-linux -> 1.3.5
  * libsndfile[core,external-libs,mpeg]:x64-linux -> 1.1.0
  * libvorbis[core]:x64-linux -> 1.3.7#2
  * mp3lame[core]:x64-linux -> 3.100#7
  * mpg123[core]:x64-linux -> 1.29.2#3
  * opus[core]:x64-linux -> 1.3.1#6
    vamp-sdk[core]:x64-linux -> 2.10#3
Additional packages (*) will be modified to complete this operation.

however, explicitly installing the libsndfile[core] does work:

./vcpkg install libsndfile[core] vamp-sdk --dry-run
Computing installation plan...
The following packages will be built and installed:
    libsndfile[core]:x64-linux -> 1.1.0
    vamp-sdk[core]:x64-linux -> 2.10#3

Is this an vcpkg-tool regression?
