Explicitly include defaults.cc in the shared_library gyp target, otherwise
the whole compilation unit is stripped by the Windows linker, since none of it's
symbols are referenced by any other compilation unit in V8.

As discussed re: https://codereview.chromium.org/24550008/, this fixes the link
error on the Window's component build. Another option would be to explicitly
reference a symbol in default.cc somewhere else in v8 (e.g., api.cc), by doing
something like:
  bool (*defaults_cc_hack)(void) =
&SetDefaultResourceConstraintsForCurrentPlatform;

Any thoughts on the preferred approach?

LGTM. 

Maybe it would be cleaner after all to merge the defaults stuff into
v8.h/api.cc.
If we don't do that, we could consider moving defaults.cc out of the v8_base
target.
