macho: add routine for creating a dynamic stub_helper atom
...
With this routine, we are now able to freely shift stub_helper
section in memory and in file since the VM addressing is now dynamically
dependent on the positioning of `__stub_helper` preamble and other
sections generated by the linker.

macho: incrementally write dyld_private and stub_helper atoms
...
By incrementally I mean using the incremental linker machinery
and concepts. Currently, lots of repetition but already highlighted
a potential problem with resolving relocations for symbols that
weren't seen yet but wanting to write the atom to file (before
seeing the relevant atoms).

macho: fix writeSymbolTable() function

After merging `populateMetadata` with `populateMissingMetadata`,
it is imperative we clear the number of symbols in `writeSymbolTable`.
However, this is hopefully just a temp measure until the convergence
of incremental with traditional is complete.
