[PATCH] build: restore -version-info

[Jan Engelhardt <jengelh@inai.de>]

There was no noticable reason to switch to -version-number;
version-number would have also seen the use of 3:0:0, not 3:0:1.

3:0:1 only makes sense with -version-info, so put "-version-info"
back. However, since ipset-6.13 already released libipset.so.3, going
back to .so.2 might not be such a good idea, so continue using .so.3
by means of 3:0:0.

Also note that the version names in libipset.map generally are not
supposed to follow SO versions, but the program version):
IPSET_6.13 {...}.
