CI: github: dump the backtrace of coredumps in the alpine container
This patch allows to show the backtrace of a coredump produced in the
alpine/musl jobs.
It activates some option required by the containers to allow the
production of coredump, set a shared directory so the kernel could dump
the coredump within the container. Some debug packages were also added.
