shell: Make shell_strlen return u16_t

Browse source 
Everywhere the return of this function was being assigned to u16_t to
save space on stack. Instead of casting in all these places (and may
end up with overflow), just changing this function's return.

Note that the function itself is not checking for overflow yet since
I'm not sure this can happen and/or is a problem. Though now we have
only one single point to fix this problem.
