meson: try iconv in libintl lookup

Browse Source 
This was originally removed in !2734 but still appears to be required for
some MinGW setups, such as the `x86_64-w64-mingw32.static` target in
[mxe](https://github.com/mxe/mxe).

Currently, this configuration fails the libintl internal assert on line
2128, as on this platform `ngettext()` is only found inside libiconv.

This commit will look up iconv potentially twice, once as `libiconv` and
potentially once as `libintl_iconv`. This is what the code did before
!2734 landed, so it’s known to work reliably on a number of platforms.
