`Symbolizer::PrepareForSandboxing` is empty for all platforms and apparently
has been for a while (https://reviews.llvm.org/D10213). Remove it, and shuffle things around so that the
platform specific code is now in `PlatformPrepareForSandboxing`.

This allows to have one less symbolizer dependency in a common file, which
helps for the upcoming split.

Also remove `SymbolizerPrepareForSandboxing` in tsan_go which appears to not
be used anywhere.
