### What problem does this PR solve?
Currently, when the Doris BE process exceed memory limit, Jemalloc cache
will be manually released.
Add the Jemalloc cache to the available memory of the BE process is expected
to have little impact on the risk of the process OOM killer. the process memory
used has already subtracted the Jemalloc cache.
