[PATCH net-next 1/2] selftests: drv-net: use env.rpath in the HDS test

[Jakub Kicinski <kuba@xxxxxxxxxx>]

Commit 29b036be1b0b ("selftests: drv-net: test XDP, HDS auto and
the ioctl path") added a new test case in the net tree, now that
this code has made its way to net-next convert it to use the env.rpath()
helper instead of manually computing the relative path.
