Say it with me: the pidfile and its parent directories should
only be writable by root unless you use supervise-daemon ;)

With `checkpath -o someuser:someuser $pidfile` in start_pre(), it can
cause DOS attacks because the now unprivelaged process can replace the
pidfile with some other pid number in it like pid 1 and cause the host
machine to crash when the daemon finally stops. Supervise-daemon can
supervise without the daemon creating a pidfile so don't export the
variable at all.

That assumes the scripts *are* using supervise-daemon, if
supervise-daemon fails to start (due to maybe some incorrect config
option *wink wink*) then OpenRC falls back to the older
start-stop-daemon and that *does* use the $pidfile. If thats the case
then the daemon will simply fail to start (yes I haven't tested if any
these packages work without $pidfile which they should since they are
specifying `supervisor=supervise-daemon`).

IMO failing to start is better than running in a potentially vulnerable
configuration.
