gn2bp: Update --proto_path and --cpp_out arg
--proto_path specify the directory in which to search for imports.
net_quic_proto and metrics_proto have files that import other files.
Get proper --proto_path from the args in the desc.
Also, update --cpp_out to follow --proto_path change.
There are 6 targets which use protoc_wrapper.py in the dependency
from cronet_package_android.
It is confirmed that they could build with this commit.
