Add mallocinfo mode to `getmemoryinfo` RPC
This adds a mode argument to `getmemoryinfo`. By default the output
will remain the same. However if a mode argument of `mallocinfo` is
provided the result of glibc `malloc_info` (if available) will
be returned as a string, as-is.
This is useful for tracking heap usage over time or troubleshooting
memory fragmentation issues.
