[LTP] [PATCH] tst_net.sh: Avoid using tst_require_drivers in legacy API

[Petr Vorel]

tst_require_drivers is only in new shell API. Avoid using it in the old API.

NOTE: there are still 9 remaining tests in the old API, e.g.
ftp-upload-stress.sh. But instead of converting them it'd be better to
spend time to reimplement the testcase:
https://github.com/linux-test-project/ltp/issues/1207

I'm not sure about usability of multicast tests (but converting them to
new shell API should be easy).
