tmpfiles.d: only 'w+' can have multiple lines for the same path

Since d0ea5c5e39dce60efbce6d86534eb9ca253440b0, all lines specifying actions
that recreate a file system object (such as 'f+, 'L+', etc ...) on the same
path were allowed. This had the bad side effect to break the tmpfiles
configuration file sorting for files defining such lines.

For example:

  # cat /etc/tmpfiles.d/a.conf
  f+ /tmp/file - - - - a.conf

  # cat /etc/tmpfiles.d/z.conf
  f+ /tmp/file - - - - z.conf

  # systemd-tmpfiles --create /etc/tmpfiles.d/{a,z}.conf
  # cat /tmp/file
  z.conf

Even though "a.conf" sorts lexicographically before "z.conf", the content of
/tmp/file was the result of the action defined in "z.conf"

This patch restores the old logic - if multiple files specify the same path,
the entry in the file with the lexicographically earliest name will be applied.
