[RFC] psymtab.c (map_symbol_filenames_psymtab): Skip shared psymtabs.

[dje@google.com (Doug Evans)]

Hi.

I don't know if this patch is correct or not.
It looked odd that partial_map_symtabs_matching_filename
and expand_symtabs_matching_via_partial skip shared symtabs but
map_symbol_filenames_psymtab does not.
