[LTP] [PATCH v2 1/1] travis: Reenable openSUSE Tumbleweed

[Petr Vorel]

openSUSE Tumbleweed was temporarily removed in fbd46736d due
faccessat2() incompatibility in libseccomp/runc used in old docker with
old kernel on Ubuntu Focal on hosts in Travis CI together with guests
with the newest glibc 2.33.

Fixing Tumbleweed required switch to podman and downloading newest runc
release (v1.0.0-rc93) which contains the fix [1], because proposed glibc
fix [2] aren't going to merged to upstream [3] nor to Tumbleweed
downstream glibc [4].

Sooner or later it will be required for more distros (Fedora, Debian
Ubuntu), but don't waste time before required.

* install slirp4netns (required for podman)

Kind regards,
Petr
