[sanitizer] Change strip_path_prefix flag behavior.
...
Previously (in tools other than TSan) the entire prefix of the path had to mach
the argument. With this change, only some suffix of the prefix has to match.
This is the same way this flag works in TSan.

[Sanitizer/ASan] Simplify the code that prints and symbolizes stack traces. Fall back to module+offset if user-provided symbolizer failed. Use weak function __asan_symbolize instead of __asan_set_symbolize_callback in ASan interface, so that we're able to symbolize reports for errors that happen before the main() is called, for example, during module initialization.
