Fix up the boot-time ldconfig handling to deal with dual object

Browse Source 
file formats.  I have added a new rc.conf variable ${ldconfig_paths_aout}
which is like ${ldconfig_paths}, but only for a.out shared libraries.

On a "standard" ELF system, the ELF ldconfig path is taken from
${ldconfig_paths}, while the a.out ldconfig path is taken from
${ldconfig_paths_aout}.

On a not-yet-converted a.out system, only the a.out ldconfig path
is set, and it is taken from ${ldconfig_paths_aout}.  If that
variable is unset, /etc/rc defaults it to the value of ${ldconfig_paths},
on the assumption that the system's "/etc/rc.conf" file hasn't been
updated.
