[bug#70843] [PATCH] guix-install.sh: Relax check for OpenRC.

[Tomas Volf]

On my virtual private servers running Alpine, the install script failed to
identify the init system.  The virtual server is LXC based, and OpenRC
identifies itself like this:

    # openrc --version
    openrc (OpenRC [LXC]) 0.52.1

The regular expression failed to match it.  After relaxing the check (by
removing the trailing `)' requirement) the installation went fine and I got
functional Guix installation.

* etc/guix-install.sh (chk_init_sys): Drop trailing \) from the regular
expression.
