sysutils/zrepl: /var/run/zrepl should not be world-readable

This partially reverts commit 2a866a1, and instead installs
the pidfile to /var/run/zrepl.pid fixing the problem seen in
PR 255981.

As taken from the zrepl documentation[1]:

[....]
The zrepl daemon needs to open various UNIX sockets in a runtime directory:

a control socket that the CLI commands use to interact with the daemon
the ssh+stdinserver Transport listener opens one socket per configured
client, named after client_identity parameter

There is no authentication on these sockets except the UNIX permissions.
The zrepl daemon will refuse to bind any of the above sockets in a
directory that is world-accessible.
