openrc-run.8: Note variables referenced by default 'start'/'stop'.

[flexibeast]

This PR updates the openrc-run.8 man page to note which variables are referenced by the default implementations of start() and stop().

In creating this PR, i found that the capabilities, no_new_privs and secbits variables, referenced by the default start() function, are not documented in openrc-run(8); is this intentional, or can i create a PR to address this?

I don't think this is intentional. PRs should be welcome.

This PR updates the openrc-run.8 man page to note which variables are referenced by the default implementations of start() and stop().

I like the idea, but:

• I don't like how it's using (*) and (**), they look ugly
• The "default" start and stop can vary based on supervisor=.

Okay. Can you suggest an alternative way of conveying this information? (As an aside, here's the situation which led me to create this PR.)

I think we can have a separate section in a table format. Something like this:

.Sh DEFAULT START STOP
The following table lists all the variables that are used by the default start
and stop functions.
.Bl -column "Variable" "start\-stop\-daemon" "supervise\-daemon" "s6" -offset indent
.It Sy "Variable" Ta Sy "start\-stop\-daemon" Ta Sy "supervise\-daemon" Ta Sy "s6"
.It "pidfile"     Ta "start,stop" Ta "start,stop" Ta ""
.El
