Go 1.21.3 fixes an important HTTP2 CVE (see CVE-2023-39325 and
CVE-2023-44487). Nomad does not use HTTP2 and is not vulnerable. However we
should pick up the toolchain bump if for no other reason than we don't have to
answer questions about that.
* build: update to go1.21
* go: eliminate helpers in favor of min/max
* build: run go mod tidy
* build: swap depguard for semgrep
* command: fixup broken tls error check on go1.21
Go released a security update to fix build-time code injection and execution via
CGO. This doesn't impact already-released versions of Nomad, just the build
toolchain, so we won't be releasing a Nomad security update to go with it.
