[Pkg-matrix-maintainers] Bug#921425: matrix-synapse: please preload libjemalloc to reduce memory consumption

Synapse eats memory when entering big rooms.

At https://github.com/matrix-org/synapse#help-synapse-eats-all-my-ram is
suggested to preload libjemalloc as a way to (in my understanding)
faster release memory temporarily used by synapse.

The other tuning option seems sensible to only mention in README.Debian
but not apply by default.

Also, I suggest to mention in long description the aggressive memory
consumption.


Thanks for considering,

 - Jonas
