I am not 100% percent sure what is happening but it seems that
newMessageFilter is async operation, result of this operation is assumed
to be used in callbacks. All other tests are doing at least 1 io operation
in between creating a filter and posting a message, and it must be enough
for newMessageFilter to complete.
Setting higher GOMAXPROCS allows Otto vm to execute received io requests
immediatly. While lower number of processes may result in events re-ordering.

I tested this change with GOMAXPROCS=1 and it passes consistently.

Test waits till synchronization is started, then interrupts network connection, wait for a failure event and restore network connection, confirming that after the connection is restored synchronization will proceed.
Network disconnect is introduced by removing default gateway, easily reversible condition.
On my local machine it takes 30 seconds for peers to reconnect after connectivity is restored. As you guess this is not an accident, and there is 30 seconds timeout for dial expiration. This dial expiration is used in p2p.Server to guarantee that peers are not dialed too often.
Additionally I added small script to Makefile to run such tests in docker environment, usage example:
```
make docker-test ARGS="./t/destructive/ -v -network=4"
```
Improve patcher tool:
* fix broken `-p` flag,
* rename it to `-b`,
* add a new `-p` flag that allows specifying the source of the patches, so that it can be used for more than just go-ethereum patches,
* make it work correctly independently of the order that options are specified in the command line.
