cbmem: map_memory: Use length modifier `j` and cast for an `off_t`  argument

cbmem currently fails to build due to `-Werror` and the following
    warning.

$ make
        cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86  -c -o cbmem.o cbmem.c
        cbmem.c: In function ‘map_memory’:
        cbmem.c:87:2: error: format ‘%zx’ expects argument of type ‘size_t’, but argument 2 has type ‘off_t’ [-Werror=format]
        […]

Casting the argument of type `off_t` to `intmax_t` and using the
    length modifier `j`

$ man 3 printf
        […]
               j      A following integer conversion corresponds to an intmax_t or uintmax_t argument.
        […]

instead of `z` as suggested in [1] and confirmed by stefanct and
    segher in #coreboot on <irc.freenode.net>, gets rid of this warning
    and should work an 32-bit and 64-bit systems, as an `off_t` fits
    into `intmax_t`.
