Provide a unified signature for ps_get_cmdline.
Prior to this change, ps_get_cmdline had different signatures for
KERNEL_LINUX vs. KERNEL_SOLARIS. This means that callers who want to
call this function would have to have an #if..#else that controlled which
variant of the function to call.
By giving them the same signature, callers don't have to worry about
that.

df: remove legacy code skipping "rootfs" monitoring
3512bb1 added code to skip duplicate reporting of `rootfs` mounted on `/`.
f9c1c5b and
f0398d0 added generic code to skip any volume mounted twice.
Depending on the order of the entries in `/etc/mtab`, reporting for `/` was
entirely skipped.
This patch basically reverts the first, non-generic patch, as it's
superseded by the 2 others.

It is very useful to collect data (or ignore) from a group of interfaces
that are similarly named - especially if the list is dynamic and it's
not feasible to update configuration each time an interface shows up or
