added GoAccess index file compatiblity to awstats_index.php.master

On my system this breaks the first entry in the menu, it links to goaindex.html but i do not have such a file.

your condition checks if there is a [DATE]/awsindex.html but for the current month there is no such folder and your condition results in goaindex.html.

i think for the current month the condition should check if a file awsindex.html exists without the [DATE]-folder-prefix.

i would suggest a much simpler condition with a reasonable default, something like this should be sufficient:

$awstatsindex = 'awsindex.html';
if(!file_exists($value.'/awsindex.html') && file_exists($value.'/goaindex.html')) $awstatsindex = 'goaindex.html';

@brt thanks for your comments. Please open a issue next time, as we can't read the comments on every commit.

@thom sorry, i already thought about opening an issue, but i was somehow unsure/busy/lazy, next time ... promised!

after fixing it through conf-custom/awstats_index.php.master so that it works on my setup, it shifted out of my focus.

No problem, thanks for your proposed fix. See #6147 (closed) and attached MR.
