vtysh: fix build failure for certain case

The build failed if two conditions are met at the same time:

1. Configure with `--disable-dependency-tracking`
2. Set an indenpendent build directory

```
anlan@host:~/frr/build$ make
make: Entering directory '/home/anlan/frr/build'
true
/usr/bin/perl ../vtysh/daemons.pl zebra bgpd ripd ripngd ospfd ospf6d isisd fabricd nhrpd ldpd babeld eigrpd  pimd pim6d pbrd staticd bfdd vrrpd pathd > vtysh/vtysh_daemons.h
/bin/bash: line 1: vtysh/vtysh_daemons.h: No such file or directory
make: *** [Makefile:17644: vtysh/vtysh_daemons.h] Error 1
make: Leaving directory '/home/anlan/frr/build'
```

`~/frr/` is source directory, `~/frr/build/` is the specified build
directory.

So, just create necessary directory - `vtysh/`.
