Replace RTLD_LOCAL with RTLD_GLOBAL

Since we have drivers which depend on each other (ie QEMU/LXC
depend on the network driver APIs), we need to use RTLD_GLOBAL
instead of RTLD_LOCAL. While this pollutes the calling binary
with many more symbols, this is no worse than if we directly
link to the drivers, and this only applies to libvirtd
