clarify ps(1) fallback of podman top

Browse Source 
Podman top falls back to executing ps(1) inside the container in the
presence of ps-specific flags.  Clarify that a bit more to help users
resolve issues when, for instance, ps(1) isn't installed in the
container.

@ -9,7 +9,7 @@ podman\-top - Display the running processes of a container
**podman container top** [*options*] *container* [*format-descriptors*]
## DESCRIPTION
Display the running processes of the container. The *format-descriptors* are ps (1) compatible AIX format descriptors but extended to print additional information, such as the seccomp mode or the effective capabilities of a given process. The descriptors can either be passed as separated arguments or as a single comma-separated argument. Note that you can also specify options and or flags of ps(1); in this case, Podman will fallback to executing ps with the specified arguments and flags in the container.

Please use the "h*" descriptors if you want to extract host-related information. For instance, `podman top $name hpid huser` to display the PID and user of the processes in the host context.
