net-im/telegram-desktop: Drop jemalloc patch

Upstream clarified; The glibc allocator causes telegram to use excessive
amounts of memory, and never free it. That's a bug.

-Allow controlling the use of jemalloc
-
-Jemalloc is often controlled through USE=jemalloc in Gentoo. Removing or
-replacing it is trivial, and I'm not aware of any particular advantages that
-come with using this allocator, especially for an IM client. Benchmarks
-regarding this allocator provide a huge variety of results depending on the
-workload and system, so it's hard to establish when this allocator provides any
-tangible advantage.
-
-Considering things like Hardened Gentoo, the user might prefer to use a more
-exploit-resistant allocator, like GrapheneOS/hardened_malloc, and I've heard
-Musl is hardening their allocator as well.
-
-I trust the user can better judge if they need this in their particular setup.
-
-If a telegram dev is reading this, feel free to drop me a message (metadata.xml
-contains the maintainer's address), if you believe it should be forced due to
-usability concerns, or if you can provide me with some context I might be
-missing. Jemalloc is currently enabled by default.
