    sockstat: Fix build reproducibility
    
    Both usr.bin/sockstat and usr.bin/sockstat/tests build the file
    src/usr.bin/sockstat/sockstat.c.  Unfortunately, they place the
    resulting object file in the same place, but produce different
    files due to paths appearing in the .debug files; this results
    in different binaries depending on how the race between the two
    builds ends.
    
    Use .PATH to tell make to find sockstat.c in the parent directory
    but place the object file in the current object directory, rather
    than placing '..' into the name of the source file.
