tests/ncdevmem: Fix double-free of queue array

netdev_bind_rx takes ownership of the queue array passed as parameter
and frees it, so a queue array buffer cannot be reused across multiple
netdev_bind_rx calls.

This commit fixes that by always passing in a newly created queue array
to all netdev_bind_rx calls in ncdevmem.

io_uring/zcrx: enable tcp-data-split in selftest

For bnxt when the agg ring is used then tcp-data-split is automatically
reported to be enabled, but __net_mp_open_rxq() requires tcp-data-split
to be explicitly enabled by the user.

Enable tcp-data-split explicitly in io_uring zc rx selftest.

selftests: net: use the dummy bpf from net/lib

Commit 29b036be1b0b ("selftests: drv-net: test XDP, HDS auto and
the ioctl path") added an sample XDP_PASS prog in net/lib, so
that we can reuse it in various sub-directories. Delete the old
sample and use the one from the lib in existing tests.

selftests: drv-net: replace the rpath helper with Path objects

The single letter + "path" helpers do not have many fans (see Link).

selftests: drv-net: replace the rpath helper with Path objects

The single letter + "path" helpers do not have many fans (see Link).
Use a Path object with a better name. test_dir is the replacement
for rpath(), net_lib_dir is a new path of the $ksft/net/lib directory.

The Path() class overloads the "/" operator and can be cast to string
automatically, so to get a path to a file tests can do:

path = env.test_dir / "binary"
