e2fsprogs: fix cross compilation problem

The checking of types in parse-types.sh doesn't make much sense in a
cross-compilation environment, because the generated binary is executed
on build machine.

So even if asm_types.h has got correct statements for types, it's possible
that the generated binary will report an error. Because these types are for
the target machine.
