golang: Update to 1.21.0, remove patch

Upstream has updated the Go compiler to not use gold when building for
arm, and is waiting for a fix to binutils (released in 2.41) before
doing the same for aarch64.[1]

Based on the above, it does not appear that
https://github.com/golang/go/pull/49748 will be merged. This removes the
patch from that pull request.

-Subject: [PATCH] cmd/link: use gold on ARM/ARM64 only if gold is available
-
-COPY relocation handling on ARM/ARM64 has been fixed in recent versions
-of the GNU linker. This switches to gold only if gold is available.
-
-Fixes #22040.
