[dockerbase]: remove apt-get clean

[lguohan]

(qiluo-msft added)
The debian jessie image updated recently (https://github.com/debuerreotype/docker-debian-artifacts/blob/0dcb9a06b2fcf9fdb416dc558db6f7b84cb6ab01/jessie/rootfs.tar.xz) and brought breaking change.
The path /var/cache/apt/archives/ is missing, and later 'apt-get clean' will fail with

E: Could not open lock file /var/cache/apt/archives/lock - open (2: No such file or directory)
E: Unable to lock the download directory

We found that 'apt-get update' will create the missing directory and files, so simple remove the 'apt-clean' to workaround this bug.

I took the new commit and still I get this error when trying to build slave image:

E: Could not open lock file /var/cache/apt/archives/lock - open (2: No such file or directory)
E: Unable to lock the download directory

dockers/docker-base/Dockerfile.j2:

COPY ["dpkg_01_drop", "/etc/dpkg/dpkg.cfg.d/01_drop"]
RUN apt-get update

## Pre-install fundamental packages

@YonatanPitz Could you double check the log file (target/docker-base.gz.log). Below is from our build server.

Hi,
I have followed the instruction in README.md, and when I got to the point of:
sudo make configure PLATFORM=p4
I've got this error.

no target dir was created and so no log, but the stdout ouput is:

Thank you,

Oh, you found a new bug in https://github.com/Azure/sonic-buildimage/blob/master/sonic-slave/Dockerfile.
The 'apt-get clean' should also be removed because recent update in 'debian:jessie' upstream image.
Sorry for the inconvenience, we will check and fix soon.
