tools: Add initial Linux Test Project container

LTP is compiled in on debian container and the binaries
then copied into another container, which is pushed to hub.

LTP does not compile on Alpine as it uses glibc specific
pthread extensions.

I tried to link LTP statically to not require a glibc based
base image but that failed too.
