This patch is opposite to D19024, which made this symbols to be hidden by default.

Unfortunately as was pointed by Sean Silva, 
looks that FreeBSD loader wants to see __start_set_modmetadata_set/__stop_set_modmetadata_set in the dynamic symbol table. 
They were not placed there because had hidden visibility.

Patch makes them to have default visibility again.
