s390: use __u{16,32,64} instead of uint{16,32,64}_t in uapi header

When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to
make sure they can be included from user-space.

Currently, zcrypt.h is excluded from the test coverage. To make it
join the compile-test, we need to fix the build errors attached below.

For a case like this, we decided to use __u{8,16,32,64} variable types
in this discussion:
