Remove duplicated ordinals in get_export_name_addr_list

Remove duplicated ordinals in
`miasm.jitter.loader.pe.get_export_name_addr_list` and update
documentation to include ordinals.

Ordinal exports are added twice and consequently duplicated in the
output. For example, for `Lab17-02.dll` from
https://github.com/mikesiko/PracticalMalwareAnalysis-Labs:

```
[('InstallRT', 268490823), ('InstallSA', 268492481), ('InstallSB', 268494994),
('PSLIST', 268464165), ('ServiceMain', 268488496), ('StartEXS', 268467915),

```
