Newer versions of 'tail' rely on inotify and after a restore 'tail' is
unhappy with the state of inotify and just stops.
This replaces 'tail' with a minimal shell based test (thanks Andrei).

Newer versions of pip use an isolated virtual environment when building
Python projects. However, when the source code of CRIT is copied into
the isolated environment, the symlink for `../lib/py` (pycriu) becomes
invalid. As a workaround, we used the `--no-build-isolation` option for
`pip install`. However, this functionality has issues in some versions
of PIP [1, 2]. To fix this problem, this patch adds separate packages
for pycriu and crit, and each package is installed independently.

When -- after restore -- sockets can't communicate, the test times out
while waiting on recvfrom(). Since the communication is local, send()
works instantaneously - so mark sockets with SOCK_NONBLOCK and report
failure if the message is not received immediately.

Check membarrier registration both ways:
1. By issuing membarrier commands and checking if they succeed.
2. By issuing MEMBARRIER_CMD_GET_REGISTRATIONS.
