[mod_dirlisting] treat README and HEADER as paths (fixes #2818) 

Treat README and HEADER as filepaths.  If absolute path, take as-is.
If relative path, then take relative to directory physical path.

This extends dir-listing.show-header and dir-listing.show-readme
feature to take a filename, which was introduced in lighttpd 1.4.43

x-ref:
  "Custom HEADER and README filepaths in mod_dirlisting are treated as relative paths instead of absolute paths when file name starts with '/'"
