On Fedora 39 with Clang 17.0.3 and ASan enabled,
RTE_PMD_EXPORT_NAME seems to be done twice for a single
lib, which results in load_drivers() returning a list
consisting of 2 drivers (e.g., ['mlx5_common_pci', '']).
image.find_by_prefix("this_pmd_name") returns 2 symbols in this case,
"mlx5_common_pci" and an empty string ''. This didn't reproduce
with clang version 16.0.6.
This patch ensures that a symbol with an empty string_value doesn't
cause an addition to the list of drivers.
