Simplify `jemalloc` setup (without perf regression)
Reland https://github.com/rust-lang/rust/pull/146627 after fixing [the performance regression](https://github.com/rust-lang/rust/pull/148851#issuecomment-3525797560) that caused it to be reverted in https://github.com/rust-lang/rust/pull/148896.
This avoids 65f0b7a (second commit in the initial PR), and adds a comment explaining why `extern crate` is needed here instead of `use` (we need to load `tikv_jemalloc_sys` from the sysroot because of https://github.com/rust-lang/cc-rs/issues/1613).
