net-test: add test for congestion control sysctls
There are various obsolete/deprecated congestion control algorithms,
like BIC, that should never be used as they're unfair/uncooperative
and bad for other devices on the network.
In particular BIC has been deprecated for a very long (12y?) time
and subsumed by Cubic. It really should be removed from the Linux kernel
but some folks want to keep it around for historical purposes
(ie. for comparisons). There have been a lot of improvements made
into Cubic (e.g. stretched ACKs and hystart).
It is also an IETF standard (RFC8312) and used by iOS and Windows
clients.
Test: gpylint2 sysctls_test.py, ran against 5.4-R ACK kernel
