tools: macOS: types.h: fix missing unsigned types

For some reason unsigned types were not added in commit 0a06fcf608dd
("build: fix kernel 5.4 on macos"), which led to bunch of hacks, like
commit 3cc57ba4627c ("uboot-sunxi: add missing type __u64") or
commit 997ff740dc44 ("uboot-mediatek: fix build on Mac OS X").

So lets add the missing unsigned types to workaround it in a bit more
maintainable way.
