runtime(netrw): fix :Explore command in terminal

There are really two issues solved here:

- The directory listing was not populating the new buffer when using
  the :Explore command. This was because the directory to open is
  determined by using expand("%:p") which includes '!/running/command' at
  the end of the string in terminal buffers.

- The :Explore command should replace the buffer, not split it. This
  because the Explore command will automatically split if the current
  buffer has been modified. According to the docs, all terminal buffers
  will have the modified flag set when a job is running.

fixes: #9862
closes: #18069
