lib/cmdline: Fix an invalid format specifier in an assertion msg
The correct format specifier for p - n (both p and n are pointers) is %td, as the type should be ptrdiff_t. This was discovered by annotating KUnit assertion macros with gcc's printf specifier, but note that gcc incorrectly suggested a %d or %ld specifier (depending on the pointer size of the architecture being built).
