testnode: Shorten partition and software path

As testnode is used inside of slapos instance, its path is already long like:
   /srv/slapgrid/slappartXY

Very often partitions are kept in:

  /srv/slapgrid/slappartXY/srv/testnode/ZZZ/inst/test0-0

Shortening it to:

  /srv/slapgrid/slappartXY/srv/testnode/ZZZ/i/t-0

minimises chance to reach limit of maximum path, often hit by sockets.

Software path

  /srv/slapgrid/slappartXY/srv/testnode/ZZZ/soft/

has been shortened to

  /srv/slapgrid/slappartXY/srv/testnode/ZZZ/s/

for consistency.
