cond.c: Normalize COND_PATH, some systems have /run not /var/run

On most modern Linux systems /run is a tmpfs that replaces /var/run.
The latter is set up as a symlink to /run by the bootmisc.so plugin.

However, Finit conditions rely on the /var/run/finit/cond prefix, which
does not exist until bootmisc.so has run, which is *after* `mount -a`
has run.  Therefore, to have working conditions before we run `mount -a`
we must normalize the path constructed by cond_path() to use either the
/run or /var/run (default) prefix.
