patch to initscripts: configure rc.modules for PC speaker (and others)

[Matthew Miller]

As probably everyone knows by now, the PC speaker beep module isn't
something that you just _have_. You need to manually insert the pcspkr
module.

Which is annoying, if you want to have it. And, this is a general problem --
there's several other things (some laptop special-feature modules, webcam
support, etc) which don't get loaded automatically even though it'd be nice
for them to.

As someone pointed out on one of the fedora lists (this one, maybe),
rc.sysinit calls /etc/rc.modules if it exists, which it doesn't, by default.
My first cut of this added that file, but then I decided it'd probably be
better to leave that alone and just insert the code into rc.sysinit, both
for backwards-compatibility (who knows what various installations have done)
and because in general the current rc.sysinit isn't broken out like that
elsewhere.
