[scarthgap][PATCH 1/1] lighttpd: Fix trailing slash on files in mod_dirlisting

[fred.w.bacon@gmail.com]

From: Fred Bacon <fred.w.bacon@gmail.com>

Fixes [YOCTO #16128]

Backport of upstream bug fix from lighttpd-1.4.75. Version 1.4.74 introduced a bug that
would append a trailing slash to files in a directory listing. When the user attempts to
download one of these files, the web browser could not save the file with a trailing
slash. As a consequence, every web browser tested would generate a random character string
for the saved file name.

Upstream-Status: Backport [1.4.75]
