fix(detector-container): properly detect container ID when using Podman

[sjinks]

Which problem is this PR solving?

When using Podman, the container detector is unable to determine the ID of the container. This happens because the detector expects /containers/<container ID> substring in the mountinfo but Podman uses /overlay-containers/<container ID> instead.

For example:

$ podman run -it --rm alpine grep hostname /proc/self/mountinfo
4282 4276 0:94 /containers/overlay-containers/b9bb2fc96c57ef741ffbaaed3c0ac16a70705ba27443ce1a7d73554c9a63d125/userdata/hostname /etc/hostname rw,nosuid,nodev,relatime - tmpfs tmpfs rw,size=6557728k,nr_inodes=1639432,mode=700,uid=1000,gid=1000,inode64

For docker:

$ docker run -it --rm alpine grep hostname /proc/self/mountinfo
4204 4195 259:2 /var/lib/docker/containers/0848110e7e6a6fe6317d104e099286860b03962119a1a124d9dd6ec4c4dc4b11/hostname /etc/hostname rw,relatime - ext4 /dev/nvme0n1p2 rw,errors=remount-ro
