contrib: dracut: zfs-snapshot-bootfs: exit status fix
When the zfs-snapshot-bootfs service attempts to create a snapshot 
that already exists, the exit status of the command is non-zero and 
the service reports failed to the systemd service manager. This is a 
common occurrence if bootfs.snapshot is left set on the kernel command 
line and it should not be considered a failure. 
 
This service was originally set to ignore this error by prefixing 
the command with - on the ExecStart line, but the leading - appears 
to have been dropped in #13359.
