[sanitizer] Remove empty Symbolizer PrepareForSandboxing

Authored by cryptoad on Mar 27 2018, 1:37 PM.



Symbolizer::PrepareForSandboxing is empty for all platforms and apparently
has been for a while (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.

Directly call PlatformPrepareForSandboxing from

Anyone else but Roland for some comments/LGTM please?
