Make ContentShell create a jar containing its .class output

Make ContentShell create a jar containing its .class output

Some other targets depend on the .java files used by content shell. We
cannot simply create a jar in the normal way since the content shell
java files may depend on the content shell resources. The Android build
system creates R.java when content_shell_apk is built. So, to create the
jar, we should just package all the output .class files from when the
apk is built.

This also adds a "fake" target content_shell_java which can be used like
all the other jar targets. That is, a target that depends on
content_shell_java will have the content_shell jar added to its
classpath automatically.
