makeqstrdata: ensure certain qstrs are as early as possible

Some qstrs like those representing binary ops such as __add__ must have
qstr numbers that fit in 8 bits. Replace the former ad-hoc method,
which sorted *other* dunder-identifiers early with a list of all
the qstrs that have this requirement.

Before this, the unix coverage build was failing when I added certain
qstrs like "<input>" for a codeop filename default value.
