isisd: fix building asla at first flex-algo config

When an color affinity is set on an interface before configuring the
flex-algorithm, the ASLA (Application Specific Link-Attribute) sub-TLV
is not build. Flex-algo fails to build the paths when a affinity
constraint is required because of the lacking of information contained
in ASLA. There are no problems when the configuration order is reversed.
For example:

> affinity-map red bit-position 1
>
> interface eth2
>  link-params
>   affinity red
>
> router isis 1
>  mpls-te on
>  flex-algo 129
>   dataplane sr-mpls
>   advertise-definition
>   affinity include-any green

In isis_link_params_update_asla(), the ASLA sub-TLV is not build when
the list of flex-algos is empty.

Update ASLA when the first flex-algorithm is configured.

yang: Added missed prefix to the frr-deviations-ietf-routing yang file

lib: mgmtd: fix too early daemon detach of mgmtd

Correct FRR startup counts on a daemon's vty socket to be open when the
parent process exits. The parent process waits for `frr_check_detach()`
to be called by the child before exiting. The problem is when the
`FRR_MANUAL_VTY_START` flag is set the vty socket was not opened but
`frr_check_detach()` was called anyway.

Instead add a bool option for `frr_check_detach()` to be called when the
socket is opened with `frr_vty_serv_start()`, and do so when "manually"
calling said function (i.e., when FRR_MANUAL_VTY_START is set).

The `FRR_MANUAL_VTY_START` flag is only set by mgmtd. The reason we
wait to open the vty socket is so that mgmtd can parse the various
daemon specific config files it has taken over, after the event loop has
started, but before we receive any possible new config from `vtysh`.
