package/go: security bump to version 1.21.2
Fixes CVE-2023-39323: Line directives ("//line") can be used to bypass the
restrictions on "//go:cgo_" directives, allowing blocked linker and compiler
flags to be passed during compilation. This can result in unexpected
execution of arbitrary code when running "go build".
go1.21.2 (released 2023-10-05) includes one security fixes to the cmd/go
package, as well as bug fixes to the compiler, the go command, the linker,
the runtime, and the runtime/metrics package.
