[CRIU] [PATCH] zdtm: Delete static/proc_self test

[Kirill Tkhai]

This test checks, that "/proc/self/ns/net" after restore
points to the same inode as before. I.e.:

Before dump: /proc/self/ns/net -> net:[4026531957]

After restore:  /proc/self/ns/net -> net:[4026531957]

But it's simply wrong. We can't do any assumption about
after-restore inode of a namespace.

So, let's kill this test.
