external/breakpad: Adapt to std::allocator parts removed in C++20

<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0174r2.html#4.2>
"Deprecating Vestigial Library Parts in C++17" deprecated, among others,
std::allocator::pointer, and
<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0619r4.html#3.9>
"Reviewing Deprecated Facilities of C++17 for C++20" removed it completely.
(And <https://gcc.gnu.org/git/?p=gcc.git;a=commit;
h=954026a7a4e6a1affd1ac5db237ccd75a3316760> "Remove redundant std::allocator
members for C++20" removed it from libstdc++ now for -std=c++2a.)

The change to src/common/memory.h was necessary in Library_crashreport:
