[PATCH] MdeModulePkg: Fix undefined reference to memcpy with XCODE5

["Vitaly Cheptsov" <cheptsov@ispras.ru>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3098

XCODE5 toolchain in NOOPT mode generates memcpy when trying
to copy PEI_CORE_FV_HANDLE structure. This breaks OVMF
compilation with XCODE5.
