selftests/bpf: Free strdup memory in xdp_hw_metadata
The strdup() function returns a pointer to a new string which is a
duplicate of the string "ifname". Memory for the new string is obtained
with malloc(), and need to be freed with free().
This patch adds this missing "free(saved_hwtstamp_ifname)" in cleanup()
to avoid a potential memory leak in xdp_hw_metadata.c.
