Includes fixes for:
* CVE-2021-44716: unbounded growth of HTTP/2 header canonicalization
  cache
* CVE-2021-44717: syscall.ForkExec error can close file descriptor 0

Added patches:
* 001-cmd-link-use-gold-on-ARM-ARM64-only-if-gold-is-available.patch:
  https://github.com/golang/go/pull/49748 backported for Go 1.17,
  this removes the requirement for the gold linker when building Go
  programs that use Go plugins on arm/arm64
