[Patch,Fortran] Copy more attributes for PROCEDURE() (PR35830)

Actually this was done on a clean trunk. With your patch I get:

  procedure(ai) :: f
                   1
Error: Array 'f' at (1) cannot have a deferred shape

Additionally copying attr.allocatable fixes this and makes the program
run properly.
Cheers,
