stream_file: change license to LGPL

This has a messy history all back to the initial commit with multiple
refactors, but it seems almost all authors agreed.

Exceptions:

2aa6acd9747: patch by someone who could not be reached. Whether or not
this code is still in mpv is unknown, but the affected code was moved to
stream.c at one point anyway.

3859bbd9fef: not sure if this is a patch by the mentioned person (I
assume not) or the committer (who agreed to LGPL), but it seems the
change is too trivial to affect copyright. It seems even the FD check
can be dropped, which I'm doing in this commit.

58846451f0e: author doesn't reply. But reverting this and letting
someone who has never seen this commit before redo it would lead to
exactly the same code. So I'm claiming that the change is not
copyrightable.
