    testsuite: c++: Allow for std::printf in g++.dg/modules/stdio-1_a.H 
[PR98529]
    
    g++.dg/modules/stdio-1_a.H currently FAILs on Solaris:
    
    FAIL: g++.dg/modules/stdio-1_a.H -std=c++17  scan-lang-dump module 
"Depset:0 decl entity:[0-9]* function_decl:'::printf'"
    FAIL: g++.dg/modules/stdio-1_a.H -std=c++2a  scan-lang-dump module 
"Depset:0 decl entity:[0-9]* function_decl:'::printf'"
    FAIL: g++.dg/modules/stdio-1_a.H -std=c++2b  scan-lang-dump module 
"Depset:0 decl entity:[0-9]* function_decl:'::printf'"
    
    The problem is that the module file doesn't contain
    
     Depset:0 decl entity:95 function_decl:'::printf'
    
    as expected by the test, but
    
     Depset:0 decl entity:26 function_decl:'::std::printf'
    
    This happens because Solaris <stdio.h> declares printf in namespace std
    as allowed by C++11, Annex D, D.5.
    
    This patch allows for both forms.
    
    Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
    x86_64-pc-linux-gnu.
