Add CanWriteToDalvikCache() check before writing a boot marker or image cache.
A new zygote process, the webview_zygote, will spawn isolated_app children,
but the process itself does not run as root and cannot write to the dalvik
cache. In order to not print SELinux avc errors, check for file-write
permission when testing to see if a boot marker or cache image or should be
written.
