Compiler warning fix.

My guess is that this fixes the warning:

/singularity/singularity-master/indra/newview/llfloaterdirectory.cpp: In
function â€˜void* createWebPanel(void*)â€™:
/singularity/singularity-master/indra/newview/llfloaterdirectory.cpp:167:
warning: â€˜createWebPanel(void*)::LLPanelDirWebâ€™ declared with
greater visibility than the type of its field
â€˜createWebPanel(void*)::LLPanelDirWeb::<anonymous>â€™
/singularity/singularity-master/indra/newview/llfloaterdirectory.cpp:167:
warning: â€˜createWebPanel(void*)::LLPanelDirWebâ€™ declared with
greater visibility than its base â€˜LLPanelDirFindâ€™

That I see in https://files.streamgrid.net/singularity/linux-i686.log
Attempted fix in Linux build and Linux32 packaging
