[PATCH net v3 2/3] selftest: netcons: refactor target creation

[Breno Leitao <leitao@debian.org>]

Extract the netconsole target creation from create_dynamic_target(), by
moving it from create_dynamic_target() into a new helper function. This
enables other tests to use the creation of netconsole targets with
arbitrary parameters and no sleep.

The new helper will be utilized by forthcoming torture-type selftests
that require dynamic target management.
