[PATCH net-next] selftests: Fix detection of nettest command in fcnal-test

[David Ahern <dsahern@kernel.org>]

From: David Ahern <dsahern@gmail.com>

Most of the tests run by fcnal-test.sh relies on the nettest command.
Rather than trying to cover all of the individual tests, check for the
binary only at the beginning.

Also removes the need for log_error which is undefined.

Fixes: 6f9d5cacfe07 ("selftests: Setup for functional tests for fib and socket lookups")
