udhcpc: revert deprecation message for -V

"-x vendor:VENDOR" will not be a trivial replacement of it:

(1) by default, we do send a vendor string ("udhcp BB_VER"),
will need code to preserve the default.

(2) -V '' currently disables vendor string. -x vendor:''
would not easily achieve that: it adds no option at all
(string options can't be empty), and default (1) would trigger.
To avoid that, we will need yet another hack to detect
-x vendor:'' and interpret that as "no vendor string at all".

IOW: removing -V is likely to increase code size, not decrease.
