Fix: Address a few minor issues identified by cppcheck
This patch addresses a number of smaller issues identified by the code inspection utility cppcheck. There are a number of identified leaks in the arm/linux/system.cc (although the function only get's called once so it is not a major problem), a few deletes in dev/x86/i8042.cc that were not array deletes, and sprintfs where the character array had one element less than needed. In the IIC tags there was a function allocating an array of longs which is in fact never used.
