modutils-initscripts: improve modutils.sh

modutils.sh reads /etc/modules to load the listed modules at boot time.
/etc/modules is generated by update-modules which scans
/etc/modules-load.d directory. However, update-modules became obsolete
because the files it generates are not used by modprobe anymore.

Hence, change modutils.sh to scan also /etc/modules-load.d/*.conf and
load the modules listed there.

Basically, the behavior is this:
 * if /etc/modules exists, load those modules;
 * if the directory /etc/modules-load.d exists, load the modules listed
   in the .conf files but ignore those already loaded (from
   /etc/modules);

orinoco-conf: remove dependencies of update-modules

Since update-modules became obsolete, no need for these dependencies.
Also:
 * install the conf files in the modprobe.d directory. /etc/modutils is
   also obsolete;
 * remove postinst/postrm scriptlets since they ran update-modules and
   this is just an alias file;

hostap-conf: remove dependencies of update-modules

Also:
 * install the alias file in the correct /etc/modprobe.d directory since
   this is the directory used by modprobe now;
 * rewrite the alias file to be up-to-date with modprobe's syntax;
 * remove the postinst/postrm scriptlets because this is just an alias
   file;

update-modules: remove recipe from oe-core

update-modules is not used anymore. Any references to it have been
removed, some time ago, from all recipes/bbclasses. It stayed in oe-core
in case anybody still wanted to use it. Time for it to go.
