Remove spurious libiconv dependencies

OS X ships with iconv. glib failed to detect it, and this snowballed
into a few formulas requiring a superfluous duplicate install of
libiconv. All of the formulas in this commit compile without the
libiconv dependency.

jn:
The libiconv shipped with 10.5, 10.6, and 10.7 is version 1.11, so there
shouldn't be any cases of "10.x needs a newer libiconv but 10.y does
not".

In any case, we'll wait a week or so just in case any weird issues crop
up, and if not, then we can remove the libiconv formula and blacklist
it.
