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.
