src: explicitly register built-in modules

Previously, built-in modules are registered before main() via
__attribute__((constructor)) mechanism in GCC and similiar
mechanism in MSVC. This causes some issues when node is built as
static library. Calling module registration function for built-in
modules in node::Init() helps to avoid the issues.
