[CRIU] [PATCH 0/6] Fixes and tests for dumpable flag (in particular handling fs.suid_dumpable=2)

[Filipe Brandenburger]

Hi Pavel,

I hope these are still in time for the 1.3.0-rc2 release tomorrow.

I created two test cases, one basic test to confirm that restoring the dumpable
flag works in the simple case and another complex one that does some gymnastics
to get a process with the dumpable flag disabled (set to either 0 or 2
depending on fs.suid_dumpable) dumped and restored by criu.

I'm also sending the revert for Saied's temporary workaround and two minor
cleanups in .gitignore files.

Cheers!
Filipe
