Back to the originally proposed name VRT_DirectorResolve()

Ref
https://github.com/varnishcache/varnish-cache/pull/3315#discussion_r429796022

OKed by phk on irc.

VRT_DirectorResolve() was the name originally proposed in #2680, which
was renamed in #3311 and accepted by me to get ahead. Not that Dridi
prefers the original name and phk goes along, we change it back before
the next release.
