Add simple Containerfile

This adds a regular container (or Docker) file which builds LTP from
source. This is initially intended for testing the LTP itself.

The resulting container has just the LTP installation and runtime
dependencies. However it is still quite large, probably due to debug
symbols.

The container can be built with a command like:

podman build -t tumbleweed/ltp \
       --build-arg PREFIX=registry.opensuse.org/opensuse/ \
       --build-arg DISTRO_NAME=tumbleweed \
       --build-arg DISTRO_RELEASE=20230925 .

Or just

podman build .

which will create an Alpine container.

It contains Kirk in /opt/kirk. So

cd /opt/kirk && ./kirk -f ltp -r syscalls

will run some tests.

Note a much smaller container can be found at:
https://registry.opensuse.org/cgi-bin/cooverview?srch_term=project%3D%5Ebenchmark+container%3D.*
This is created with SUSE's build system which does not use container files
