test-hardlink: do not test .hg/cache/checklink

Linux and BSD have different behavior on "os.link(src, dst)" where "src" is
a symlink. That causes test difference.

According to POSIX [1]:

  If path1 names a symbolic link, it is implementation-defined whether
  link() follows the symbolic link, or creates a new link to the symbolic
  link itself.

So both behaviors are correct. This patch removes the trouble maker
"checklink" to make the test pass on both platforms.
