printf: Convert %l to %ll
In order to make our printf more standard, utilize %ll for long long
arguments, rather than %l. This does cost a little bit in flash space
for that extra l in a couple of places, but enables us to turn on
compile-time printf format checking.
For this commit only, the semantics are such that both %l and %ll
take 64-bit arguments. In the next commit, %l goes to its correct
behavior of taking a sizeof(long) argument.
