libxbps::xbps_humanize_number(): use common values and hide implementation details from API.

Browse Source 
So now its prototype is the following:

int xbps_humanize_number(char *buf, int64_t bytes)

It is a wrapper around NetBSD's humanize_number(3) which uses 6 digits for max
length, HN_AUTOSCALE and HN_NOSPACE|HN_DECIMAL. All users have been updated.
