COFF, ELF2: Pass output file path implicitly using Config global variable.

Various parameters are passed implicitly using Config global variable
already. Output file path is no different from others, so there was no
special reason to handle that differnetly.

to writeResult(SymbolTable *).

For now we only have on Chunk type. Simplify.

The others we have in sight are
* common symbols.
* entries in SHF_MERGE sections.
They will have a substantially different treatment. It is not clear if it is
worth it putting them all in a single list just to dispatch based on the kind on
the other side.
I hope to implement common symbols soon, and then we will be in a position
to have a concrete discussion. For now this is simpler for the the implemented
features.
