libpayload: fix size_t handling

libcbfs was using printf for size_t typed variables. However, printf
    did not support printing those. This patch fixes the issue, removing
    the warning when compiling ram_media.c

libcbfs/ram_media.c:52:10: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat]
    libcbfs/ram_media.c:52:10: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' [-Wformat]
