BaseTools' BaseTypes.h defined the ENCODE_ERROR macro as
whereas MdePkg defines it as
When building with GCC 6.3 (at least) the former triggers
"error: overflow in implicit constant conversion [-Werror=overflow]"
Resolve this by aligning it with the latter one.
This also requires aligning the BaseTools typedef of RETURN_STATUS with
the MdePkg one: INTN -> UINTN.
Add an explicit initialization of *Alignment to 0 in GenFfs.c
GetAlignmentFromFile to get rid of a warning occuring with GCC after
this change (-Werror=maybe-uninitialized).
