[C++] Don't install jemalloc in parallel #17316
Description
On ARROW-6437 (#7928) we saw occasional "File exists" errors on jemalloc_ep on macOS. Googling the error message led back to ARROW-739 (#456), which fixed this before by forcing install with -j1. ARROW-3492 later made it so jemalloc would build (but not install) in parallel. Then ARROW-3539 (#2779) was addressing a problem with that change and, along with fixing the build parallelization issue, unfortunately reverted the original make -j1 install fix.
