[Patch, Fortran] PR54221 - mark private module vars/procs as TREE_PUBLIC()=0

[Tobias Burnus]

Since April, gfortran no longer marks module procedures/variables as 
TREE_PUBLIC, if they are marked as PRIVATE. (-> improved optimization, 
reduced file size)

However, as this PR shows, for "PRIVATE" instead of "PRIVATE :: symbol" 
this didn't work, which is addressed by the attached patch.

I only included a test case for module variables; for module procedures, 
one runs into PR54224.

Build and regtested on x86-64-linux.
OK for the trunk?
