Subject: [PATCH] libzigc: add missing __dup3() symbol

This was missed in ff612334fa (https://codeberg.org/ziglang/zig/pulls/31803).
Please don't forget these weak aliases when deleting musl code; doing so can
cause portions of code in musl to fail to link. For example, this particular
case broke freopen().
