[Android] Fix path to ping on Android API 21-27

[simonrozsival]

The path to the ping binary on Android is /system/bin/ping. Newer Androids (API 28+) have a symlink for /bin -> /system/bin, so our CI that runs tests on API 29 didn't catch it.

Ref #78990

@simonrozsival should we backport this?

[simonrozsival]

I didn't think it's worth backporting but now that I've given it another thought I think we should backport it to both .NET 6 and 7.
