cpukit/libmisc/shell/main_mdump.c: Use uintptr_t to print address

Browse Source 
The behavior of the %p printf() specifier is implementation
dependent. The behavior varies on RTEMS between printf() and
printk(). This change prints an address as a uintptr_t to
ensure formatting is consistent. It also adjusts the output
width based on target architecture pointer size.
