Andreas Florath fa6c731132 Move fstrim to block device layer
The call to fstrim in disk-image-create is currently useless, because
at the time this is called, the file systems were already umounted by
the block device layer.

The current implementation of the block-device mount plugin does not
call fstrim at all: resulting in larger image sizes.

This patch removes the useless fstrim call from the disk-image-create
script and moves this into the block-device mount.py.

The resulting image might be much smaller.  Example: Ubuntu Xenial
with some elements; once with and once without this patch:

-rw-r--r-- 1 dib dib 475661824 Sep 16 06:43 ubuntu-xenial-without-fstrim.qcow2
-rw-r--r-- 1 dib dib 364249088 Sep 16 09:30 ubuntu-xenial-with-fstrim.qcow2
