Since unmet_dependencies stores integers, represent them as int

Since unmet_dependencies only ever contains strings that are integers
written out in decimal, store the integer instead. Do this
unconditionally since it doesn't cost any extra memory.

This commit saves a little memory and more importantly avoids a gotcha
with uninitialized pointers which caused a bug on development (the
array was only initialized in verbose mode).
