[sanitizer] Skip /include/c++/ from summary (#78534)
std:: usually is not a cause of the bug.
We now display
```
SUMMARY: AddressSanitizer: allocation-size-too-big path/to/allocator_returns_null.cpp:92:7 in main
```
instead of
```
SUMMARY: AddressSanitizer: allocation-size-too-big /usr/lib/../include/c++/13/bits/new_allocator.h:147:27 in std::__new_allocator<char>::allocate(unsigned long, void const*)
```
`/include/c++/` matches both libc++ and libstdc++ include paths.
