libnl_1.1.bb: Fix the build when libnl2 is staged

Currently linker would search for libnl in sysroot
first before linking in the one thats build with libnl
this patch directs ld to link in with the one thats
build and not look for the one in sysroot.

As a result we can compile libnl and libnl2 alongside
