[Buildroot] [git commit] size-stats: fix bug when parsing file names with comma

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=34b1bdeba40bf303dc8821421745d5b38a729984
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The size-stats script fails when the usb_modeswitch_data is enabled,
because this package installs files that contain commas in their
name. However, the size-stats script also uses comma as a separator for
its CSV files, causing a "ValueError: too many values to unpack" in:

  pkg, fpath = l.split(",")

Fix this by splitting only the two fields that need to be split.

The bug was reported by Matthias <porto.rio at gmx.net>, who also suggested
a fix.

Fixes bug #9136.
