Michael Eischer fe43f53528 mount: enable fuse readahead 
Apparently readahead was disabled by default. Enable readahead with the
Linux default size of 128kB. Larger values seem to have no effect.
This can speed up reading from the fuse mount by at least factor 5.

Speedup for a 1G random file stored in a local repository:
(Only one result shown, but times were quite stable, restarted restic
after each command)
