Constrain the ".." filter to exclude "..somefile"

https://www.exim.org/exim-html-current/doc/html/spec_html/ch-file_and_database_lookups.html

> The match value is one of "file", "dir" or "subdir" (the latter not matching 
> "." or "..").

A provisional patch is included in https://bugs.exim.org/show_bug.cgi?id=2916
where it is combined with other improvements.

This bug report is constrained to reporting the issue that the code does not
match the documentation, and proposing a fix.
