perfetto-extras is a phony module that abstracts optional components for
perfetto. Previously, the dependencies were installed by directly
required from traced_probes.
But that is expected to interfere with an upcoming change in Soong where
`required` dependencies are installed by Soong. Specifically, it will
increase the size of the `microdroid` module by 2-3MB because the
dependencies - which are unnecessary in Microdroid - will be installed
there due to the `required` being effective in Soong.
This change fixes that regression by making the dependencies to be only
for Android.
Bug: 321626681
Test: check the dependencies are found in Android
Test: check the dependencies are absent in Microdroid
