Heh :) This patch results in a weird effect. Look:

	# ./test/zdtm.py run -t zdtm/static/env00 -f h --keep-img always
	...
	# ls dump/zdtm/static/env00/39/1/
	...
	unixsk.img

The problem is that the amount of unix sockets involved in env00 test is zero,
but for some reason sk-unix.c decides to write into images one external unix sk
entry which is not referenced by anybody.

The patch id is c085d6af6d5, merged into 2.4.
