binman: Use unsigned long over typedef ulong

The header binman_sym.h depends on ulong typedef but does not include
types.h. This means the header must be included after including types.h
or a header that includes it.

We could include types.h but instead let's just switch from ulong
to directly using unsigned long. This removes the need for typedef'ing
it in some of the tests, so also remove those.
