    test: limit number of arenas in vmem_stats

    By default, jemalloc allocates 4 * num_of_cpu arenas. If statistics

    are enabled, it also allocates the corresponding per-arena stat

    structures for all the arenas, even if only one arena is actually used

    (single-threaded program).  If this test is run on a machine with

    the number of cores >=64, the amount of memory required to keep all

    the statistics is larger than the usable space of the pool.

    The easiest workaround is to limit the number of arenas for this test

    by setting JE_VMEM_MALLOC_CONF environment variable.  Thus, the test can

    be run on any machine and we don't need to calculate the pool size

    based on number of available CPU cores.

    Backported from master (ccbf4cb).
