C4::Circulation - ensure that certain modules always get imported

For some reason currently unclear to me, a use 'C4::XXX' does
not seem to guarantee that the contents of C4::XXX's
@EXPORT gets imported into C4::Circulation's symbol table.

Added an INIT block to ensure that this gets done as
part of runtime initialization.
