Johannes Schlatow 07736d1689 test/memcpy: fix optimistic results on Linux
When executed on Linux, the test was impaired by the copy-on-write
optimisation since the source buffer was never initialised. By default,
Linux only maps a zeroed page until the first write access to the page
occurs. Since the source buffer was never written, the corresponding
page was always present in the physically-indexed data cache. In
consequence, the test merely measured write performance (similar to memset).
