[Docs] Correct description of lldbinit behavior

Jim pointed out that "every time somebody has touched the documentation
on startup files they have stated that we source the application one and
then the global one, even though in actual fact we’ve never done that."

Indeed, when we read the application specific .lldbinit file, the global
one is not read. This patch updates the man page to reflect that.
