[FIX] osv: binary size already in human format

In version 8.0, postgresql's pg_size_pretty function is used
(http://www.postgresql.org/docs/9.4/static/functions-admin.html) when
getting the size of a binary field when reading if `bin_size`
or `bin_size_[col_name]` is set in the context.

So in 8.0 the size of a binary field get units bytes, kB, MB, GB and TB
which was not taken into account. e.g: '5.3 GB'.

This fix uses the size of the string to choose to differenciate the two.

e.g: '10000 bytes' (the longest size) will be returned directly, but
for something longer the human size of the content length will be

There is a corner case if a file is shorter than 12 bytes but
it is an enough of a small scenario with small implications that it is
deemed acceptable.
