The remote editor allows to read/write from/to a remote file. This
change:
- Adds new binder API `writeFile`.
- Update fd_server to serve a read/writable fd. Read operation is done
through the existing read API when applicable.
- Adds `RemoteFileEditor` as a binder client for both read and write.

Note that authfs is added to the "direct" apex image temporarily (instead
of microdroid) to unblock integration test within Android. Once binder
across the VM boundary is supported and authfs is updated, it should be
moved to microdroid.

fd_server provides a binder service (currently local binder since remote
binder is not ready). The server starts with FDs specified in the
command line flags (and supposedly opened FDs passed from the parent
process).
fd_server is supposed to run in Android to provide backing file to
authfs.
Test: # Start the server to serve the file. Read from the client.
adb shell 'exec
9</system/bin/sh
