Matt Heon 3560ccd5df Detect unhandled reboots and require user intervention 
Podman needs to be able to detect when a system reboot occurs to
do certain types of cleanup operation (for example, reset
container states, clean up IPAM allocations, etc). our current
method for this is a sentinel file on a tmpfs filesystem. The
problem emerges that there is no directory that is guaranteed to
be a tmpfs and is also guaranteed to be accessible to rootless
users in the FHS. If the user has a systemd user session, we can
depend on /run/user/$UID, but we can't reliably say that they do.

This code will detect the no-tmpfs-but-reboot-occurred case by
writing the current system boot ID to our tmpfs sentinel file
when it is created, and checking that file every time Podman
starts to make sure that the current boot ID matches the cached
one in the sentinel file. If they don't match, a reboot occurred
and the sentinel file was not on a tmpfs and thus survived. In
that case, throw an error telling the user to remove certain
directories (the ones that are supposed to be tmpfs), so we can
proceed as expected.
