tests: Pim vrf's need 4.19 or better to run properly not 4.15

Browse Source 
Tests are failing in micronet because linux kernel needs are 4.19
not 4.15

Notice the missing pimreg11 device needed in vrf blue:

While on a 5.4 machine we have this:

mininet310# show int brief
Interface       Status  VRF             Addresses
---------       ------  ---             ---------
blue            up      blue
dummy1          up      blue
dummy2          up      blue
pimreg11        up      blue

As such let's limit the test to a 4.19 kernel or above that our
documentations states we need for proper pim operation.
