[sanitizer] Check if directory exists before trying to create
Add a DirExists mechanism, modeled after FileExists. Use it to guard

This should avoid failures running the sanitizer in a sandbox where the
file creation attempt causes hard failures, even for an existing
directory. Problem reported on D109794 for ChromeOS in sandbox
