Ticket #4559: extfs: u7z: bug with nested dirs in mkdir action. 

The -w option sets the working directory for the temporary archive 7-zip
builds when modifying an existing one. The option cant be used to set
the base path inside an archive when adding something into it.

When adding something to a 7z archive by its absolute path, 7zip only
uses the last part of the path by default. E.g. `7z a 1.7z
/tmp/a/b/date.txt` would add date.txt to the root dir inside the
archive. If we wanted the file to be under `a/b/` inside the archive as
well, it should be `7z a 1.7z /tmp/a`.

Closes MidnightCommander/mc#202.
