dev-lang/ruby: fix build issue with gcc15

1. if USE="socks5", full protoype is required by C23
2. if CFLAGS="-flto -Werror=lto-type-mismatch", and building with
   -std=c23 (default for gcc 15), build will fail with"
   "static declaration of ‘rb_io_closed_p’ follows non-static declaration"

all patches are from upstream (w/ minor change if backport)
