The `OutputSection::appendSection()` method always gets a pointer
to the `Section` class descendants. So it is not necessary to keep them
in the vector of `Chunk` pointers.
No functional changes.

There's (almost) never need to keep .L symbols around for production
builds. In fact, the FreeBSD kernel explicitly specify -X beacuse the
size impact (and the subsequent performance impact) might be significant,
because we keep symbols in memory.
I was tempted to make this the default, but I haven't (yet).
