Josh Gao 7d58607360 adb: shell: add -n flag to not read from stdin.
Shell scripts of the following form do not work properly with adb:
    echo "foo\nbar\nbaz" | {
        read FOO
        while [ "$FOO" != "" ]; do
            adb shell echo $FOO
            read FOO
        done
    }
The first run of adb shell will consume all of the contents of stdin,
causing the loop to immediately end. ssh solves this by providing a -n
flag that causes it to not read from stdin. This commit adds the same.
