oleaut32: Fix memcpy overlapping ranges in SysReAllocStringLen (valgrind)

[Jon Griffiths]

Hi,

Since HeapReAlloc() may return us the same block, memcpy may overlap, so use memmove instead. Fixes:

Source and destination overlap in memcpy at memcpy
by SysReAllocStringLen (oleaut.c:304)
by test_SysReAllocStringLen (vartype.c:5258)

Cheers
Jon
