pkg/csource: enforce the bit size of -1
syscall() is a variadic function, so we need to be careful when passing
const values in there without specifying their type.
For -1, we did not specify it, and on 64 bit architectures the de facto
passed value was 0xFFFFFFFF instead of 0xFFFFFFFFFFFFFFFF. Fix it and
add a test.
Closes #5921.
