wrk: update to 4.1.0.

This includes a patch to adjust zmalloc's prefix size so that the
memory following it is aligned correctly. This is to prevent a SIGBUS
on armv[5-7] systems when wrk increments its stats counters.

+Subject: [PATCH] [PATCH] wrk: Fix zmalloc prefix alignment
+
+Adjust zmalloc's prefix size so that whatever follows the prefix stays
+8- or 16-byte aligned.
+
+This mainly affects ARM systems where size_t is 4 bytes. That causes
+data following the prefix to be misaligned by 4 bytes. The effect of
+this is only noticeable when wrk performs an atomic increment on memory
+allocated for its statistics. Since wrk uses uint64_t counters (8-byte
+aligned), the counters end up being offset by 4 bytes. As a result, when
+wrk uses a __sync_fetch_and_add on one of its counters, it raises
+a SIGBUS.
+
+This patch is based on <https://github.com/wg/wrk/pull/154>.
