[PATCH net-next] selftests: net: py: give bpftrace more time to start

[Jakub Kicinski]

After commit under Fixes debug runners in the CI hit the following:

  # subprocess.TimeoutExpired: Command '['bpftrace', '-f', 'json', '-q', '-e', 'kprobe:netpoll_poll_dev { @hits = count(); } interval:s:10 { exit(); }']' timed out after 15 seconds
  # # Exception| net.lib.py.ksft.KsftFailEx: bpftrace failed to run!?: {}

in netpoll_basic.py >10% of the time. Let's give bpftool more time
to start, it can take a while on a debug kernel.

Fixes: 82562972b854 ("selftests: net: pass bpftrace timeout to cmd()")
