* Returns fixed case file name to actual case on disk for case-sensitive filesystems (Linux).
* This is actually copy of cf_FindRealFileNameCaseInsensitive() from CFILE.
* @param fname the fixed case name to map to reality
* @param directory optional directory to search within (default - current path)
* @return filename with actual case name or empty path if there no mapping in filesystem
* @note This function returns only filename without directory part, i.e.
* mod_FindRealFileNameCaseInsensitive("test/test.txt") will return only "test.txt" on success.
