Use ping from alpine

Browse Source 
As of this commit, in Fedora 33, without without `CAP_NET_ADMIN` and
`CAP_NET_RAW`, require setting `net.ipv3.ping_group_range` in order for
the `ping` command to work inside a container.  However, not all images
`ping` are created equal.  For whatever reason, the busybox version in
the busybox container image, does not function.  Switch to the Alpine
image's busybox ping, which seems to work fine.
