Fix dependency issue in content_common (gyp)

Fix dependency issue in content_common (gyp)

content/public/common/common_param_traits_macros.h includes a
generated header from blink.gyp:mojo_bindings. This means anyone that
depends upon content_common must also depend upon
blink.gyp:mojo_bindings, otherwise the header may not have been
generated and you get a compile error.

The gn build deals with this already by using public_deps.
