Move the Linux zygote stuff into its own per-process directory.

The zygote is really a separate process and doesn't belong in the browser
subdirectory. I separated out the common constants used for communication into
content/[public/]/common so the zygote code doesn't depend on browser.

This leaves zygote_main_linux alone in its own directory. I'm going to be doing
some more refactoring and probably adding a new file or two here. This does
not yet add a new build target for the zygot process.
