[PATCH 2/2] build: add backwards compatibility for wildcarding nested drivers

[Kevin Traynor]

Up until DPDK 25.03 'net/*' could be used with meson options
enable_drivers or disable_drivers to explicitly enable or
disable all net drivers.

In DPDK 25.03 commit
c1d145834f28 ("net/intel: move Intel drivers to a subdirectory")
moved Intel drivers to 'net/intel/*' and 'net/*' no longer enabled
or disabled the Intel drivers.

Expand wildcards handling to include nested drivers.
e.g. 'net/*' will also enable/disable drivers in 'net/*/*'

This adds backwards compatibility so that so that 'net/*' will
continue to enable/disable Intel and any future nested drivers.
