Eclipse generator now uses compiler's default include dirs.

This adds support to the Eclipse gyp generator for detecting the
compiler's default include directories and adding them to the list of
include dirs. This finally fixes a long-standing bug where size_t was
not defined in the Android Eclipse setup.
