efi_loader: Add guidcpy function

Browse Source 
Add guidcpy function to copy the source guid to the destination
guid. Use this function instead of memcpy for copying to the
destination guid.

Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org>

Use void * instead of efi_guid_t * for arguments to allow copying unaligned
GUIDs. The GUIDs of configuration tables are __packed.
