Subject: [PATCH] src/mp4track.cpp: replace nullptr by NULL

Commit 15ec11166ba9ee7b77631d0d9234522f656cfd66 added code that uses
nullptr. nullptr is C++11, it will break the build with gcc < 5.

Semantically, NULL and nullptr are different, so should not be mixed.
In this situaiton, m_File.FindAtom() indeed does not return nullptr,
but NULL (on error, that is).

Switch back to comparing against NULL.

Fixes:
