[Patch, Fortran] PR 49265 - allow :: for "procedure :: list"

- Subject: [Patch, Fortran] PR 49265 - allow :: for "procedure :: list"
Fortran 2008 now also allows the "::" in module interfaces: "[module]
procedure [::] procedure-name-list"
The bug is also a sign for bad quality assurance as we previously only
fixed the issue for "module procedure" and not also for "procedure".
Build and regtested on x86-64-linux.
OK for the trunk?
