cmake/rgw: forward spawn's compile options to rgw_common object library

since rgw_common is an OBJECT library, we can't use
target_link_libraries() for its dependency on spawn. we add its
include directories manually already with
$<TARGET_PROPERTY:spawn,INTERFACE_INCLUDE_DIRECTORIES>, but this didn't
pull in the compile definitions. this ultimately prevented the
WITH_BOOST_VALGRIND option from passing the BOOST_USE_VALGRIND
definition attached to boost::context
