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.

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.
