receiver: Use std::vector for gr_complex
On GNU Radio HEAD the type gr_complex is not POD so it cannot be placed
inside a variable size array. This change makes rhh_temp a std::vector
instead to fix this issue.
If this function is performance critical rhh_temp should probably be
made into a max-size array and put on the top of the stack instead.
