  1. Set LIBFFI_TMPDIR at startup (elastic#80651) 

    Today if `libffi` cannot allocate pages of memory which are both
writeable and executable then it will attempt to write code to a
temporary file. Elasticsearch configures itself a suitable temporary
directory for use by JNA but by default `libffi` won't find this
directory and will try various other places. In certain configurations,
none of the other places that `libffi` tries are suitable. With older
versions of JNA this would result in a `SIGSEGV`; since elastic#80617 the JVM
will exit with an exception.

With this commit we use the `LIBFFI_TMPDIR` environment variable to
configure `libffi` to use the same directory as JNA for its temporary
files if they are needed.
