Subject: main: sanitize commas from fsname

The cipherdir path is used as the fsname, as displayed
in "df -T". Now, having a comma in fsname triggers a sanity check
in go-fuse, aborting the mount with:

  /bin/fusermount: mount failed: Invalid argument
  fuse.NewServer failed: fusermount exited with code 256

Sanitize fsname by replacing any commas with underscores.
