Auto merge of #133792 - lqd:jemallocup, r=Mark-Simulacrum

switch `jemalloc-sys` back to `tikv-jemalloc-sys`, and update to 0.6.0

Some context:
- we used to use jemalloc bindings from https://github.com/gnzlbg/jemallocator, since #55238
- that crate was abandoned, picked up as a fork in https://github.com/tikv/jemallocator, so we switched to that in #83152.
- then they were able to publish to the original `jemalloc-sys` bindings crate, and `jemalloc-sys` and `tikv-jemalloc-sys` became the same thing -- so I switched back to the OG crate in #96790
- they're now having publishing problems again: I've been waiting for https://github.com/tikv/jemallocator/pull/96 for the `jemalloc-sys` 0.6.0 update for a few months, but `tikv-jemalloc-sys` is already updated to 0.6.0.

A perf run showed some improvements, so this PR switches back to `tikv-jemalloc-sys` to update to 0.6.0.
