Following up on r1886774, ensure that when we close the file in the install
stream, the corresponding `file` field is always set to NULL.
In other words, keep the internal state consistent, even though we don't
currently retry calls such as svn_stream__install_stream() or
svn_stream__install_delete().
* subversion/libsvn_subr/stream.c
(install_stream_close_file): New helper function. Close the underlying file
of the install stream and set the corresponding `file` field to NULL.
(svn_stream__install_finalize,
svn_stream__install_stream,
svn_stream__install_delete): Use the new helper to close the file.
