Humanize size output of `apk info`

This commits adds a function for receiving the closet byte unit and the
size in that unit for a given size_t. The function doesn't return a
string since dynamic memory allocation (or a static buffer) would be
required to implement this properly.

Discussion: It might be useful to add a command line flag for disabling
this behaviour in order to retain compatibility with the previous apk
info output format.
