tests: regression: allow to run tests from anywhere

Since 357d8cf "tests: use the src/nft binary instead of $PATH one", the
tests script needs to be executed from nftables repository root. Now
the script can be run from any location and also checks the binary
existence.

To run a single test file, the path must be relative from the directory
where you launch the script.
