Syscall arguments are abi_long in user code, and plugin syscall
interface works with uint64_t only.
According to C integer promotion rules, the value is sign extended
before becoming unsigned, thus setting high bits when only 32-bit lower
ones should have a significant value.
As a result, we need to clamp values we receive from user-code
accordingly.
