[committed] test-memcpy: Actually reverse source and destination

[committed] test-memcpy: Actually reverse source and destination

[Siddhesh Poyarekar]

Looks like an oversight in memcpy tests resulted in s2 and s1 not being
swapped for the second iteration of the memcpy test.  Fix it.  Also fix
a formatting nit.
