cmd/internal/goobj: store relocation type as uint16
Currently, relocation type is stored as uint8 in object files, as
Go relocations do not exceed 255. In the linker, however, it is
used as a 16-bit type, because external relocations can exceed
255. The linker has to store the extra byte in a side table. This
complicates many things.
Just store it as uint16 in object files. This simplifies things,
with a small cost of increasing the object file sizes.
