Christian Hoffmann 36e3b2a923 textfile: use opened file's mtime as timestamp (#1326) 
Previously, the node_textfile_mtime_seconds metric was based on the
Fileinfo.ModTime() of the ioutil.ReadDir() return value. This is based
on lstat() and therefore has unintended consequences for symlinks
(modification time of the symlink instead of the symlink target is
returned). It is also racy as the lstat() is performed before reading
the file.

This commit changes the node_textfile_mtime_seconds metric to be based
on a fresh Stat() call on the open file.  This eliminates the race and
works as expected for symlinks. Fixes #1324.
