Bugfix: Do not crash with Synology NAS sftp server
It was found that when restic is used to store data on an sftp server on a
Synology NAS with a relative path (one which does not start with a slash), it
may go into an endless loop trying to create directories on the server. We've
fixed this bug by using a function in the sftp library instead of our own
implementation.
The bug was discovered because the Synology sftp server behaves erratic with
non-absolute path (e.g. `home/restic-repo`). This can be resolved by just using
an absolute path instead (`/home/restic-repo`). We've also added a paragraph in
the FAQ.
