[M108 Migration][VD] Do not overwrite process title with symbolic link

In Chromium-efl, we exec from /usr/lib/chromium-efl/efl_webprocess.
Therefore, we don't need to overwrite process title with symbolic link
of /proc/self/exe.

Before this patch, /proc/[pid]/comm of browser app is 'launchpad-loader'.
After this patch, it will be 'browser'.
