[Sanitizer] Unify summary reporting across all sanitizers.

This change unifies the summary printing across sanitizers:
now each tool uses specific version of ReportErrorSummary() method,
which deals with symbolization of the top frame and formatting a
summary message. This change modifies the summary line for ASan+LSan mode:
now the summary mentions "AddressSanitizer" instead of "LeakSanitizer".

[sanitizer] Switch to an older version of struct iocb that is found in the latest Android NDK.
