Rename kBeta to be unique (net/)

When building using Jumbo unnamed namespaces gets merged
and variables with the same name conflict. This happens
for the variables kBeta in:
net/third_party/quic/core/congestion_control/cubic_bytes.cc
net/third_party/quic/core/congestion_control/rtt_stats.cc

This commit solves the issue by renaming kBeta in
net/third_party/quic/core/congestion_control/cubic_bytes.cc
to kDefaultCubicBackoffFactor to avoid the conflict and
to give the variable a more descriptive name.
