[LTP] [PATCH] Add simple Containerfile

[Richard Palethorpe]

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 -t alpine/ltp .

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

RFC comments:
    * Add git clean -fdX which should remove any build artifacts
      this is different from the suggestion of just doing a check. I just
      found it easier to remove the build files.
    * Added seperate alpine and tumbleweed runtime scripts. Again it's
      different from the suggestion just because it's easier to add
      seperate scripts than adding a switch
    * Obviously a number of distros are missing runtime scripts. They can
      be added when someone is motivated to do so.
