Fix Makefile.am breakage

* Quash warning "Linking the executable hubo-read against the loadable module libhuboparams.so is not portable!"  I assume making libhuboparams.so a loadable module was unintentional.  Otherwise, one should probably link with dlopen() or equivalent.

* Install everything under $prefix.  It's better to put things where the user asks, rather than dropping various files under / and /usr.

* SysV init scripts go under etc/init.d, not bin.  Perhaps a symlink under bin would be reasonable.
