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.

build: fix ninja install on FreeBSD The post-install script to symlink the PMDs from their own PMD directory to the regular lib directory (so they would be found by ld at runtime) was using the "-r" flag to ln to create relative symlinks. This flag is unsupported by ln on FreeBSD causing the ninja install step to fail. Reworking the script to take the relative driver path as parameter removes the need for ln to calculate the relative path ensuring compatibility with FreeBSD. As part of the fix, we move the registration of the install script to the config/meson.build file, from the top level one. This improves readability as the script takes as parameters the variables set in that file.
