autotools.bbclass: Set the dynamic linker search path for libtool correctly

libtool obtains the search path from /etc/ld.so.conf and hardcodes /usr/lib
and /lib. This results in host contamination and variable sets of RPATH
values ending up in binaries.

By exporting the correct values for all autotools recipes we avoid this.
