build: symlink drivers to library directory With the introduction of bus drivers, we now have a situation where driver libraries will start to depend upon each other. Because of this, the driver libs need to be discoverable by the dynamic loader. There are three options to fix this: 1. Force the user to put the $libdir/dpdk/drivers folder into their library path. 2. Move all libraries from drivers sub-directory to $libdir. 3. Symlink all libraries from the subfolder to the main library dir. Option 1 is not great for usability or distro packaging, and option 2 means that we can't have EAL load all drivers from a known path automatically (as it would error out on non-PMD libs), so option 3 was chosen as the best fix. The only downside is that on a "ninja uninstall" the symlinks are not removed, as they are unknown to meson/ninja.
