libsdl2 @2.30.1: Missing libiconv dependency

[ryandesign (Ryan Carsten Schmidt)]

libsdl2 declares no dependencies:

% port deps libsdl2
libsdl2 @2.30.1_0 has no dependencies.

but on my system it is linked with /opt/local/lib/libiconv.2.dylib:

% otool -L /opt/local/lib/libSDL2.dylib

% port -qv installed libsdl2
  libsdl2 @2.30.1_0 (active) requested_variants='' platform='darwin 21' archs='x86_64' date='2024-03-09T23:03:54-0600'

so it seems like a libiconv dependency should be added.
