[Buildroot] [PATCH 1/1] utils/scanpypi: workaround for pypi project names

[Flaviu Nistor <flaviu.nistor@gmail.com>]

Add a dictionary for buildroot packages that have a different
name compared to the pypi project name (e.g. smmap2 -> smmap).
Since it is not intended to change the buildroot package name,
this is a workaround in order to use the scanpypi utility for
this packages and still get correct generated files. Current
packages added in the dictionary by this commit are smmap2 and
gitdb2.
