This script inspects an ELF file (binary or shared library) and its
linked dependencies by following DT_NEEDED tags.
So far a simple librte_pmd prefix was used as a filter.
Now that we changed the driver library names, update this heuristic with
an explicit list of all driver classes.
Fixes: a20b2c01a7a1 ("build: standardize component names and defines")

Changelog since v1:
- moved driver classes list as a class variable and did some cosmetic
change for readibility,
- used dpdk_driver_classes variable name in the hope that someone changing
meson will catch this script too,
- added bus, common, mempool and raw driver classes as some of them do
carry some pmdinfo stuff and were skipped so far but I found no
indication this skipping was intended,
