std: Disable usage of mmap allocator in libbacktrace
This is sort of a long overdue change from the investigation in #29293 and #37477. The released binaries of rustc don't have debug information and so don't actively suffer this problem but this can hit local development of rustc and also larger programs compiled against libstd generating backtraces. The main purpose of the mmap allocator in libacktrace is to be usable from a signal handler, but we don't do that, so the normal allocator using malloc/free should work well for us.
