Add checksec to CI

[psilva-veeam]

Is your feature request related to a problem? Please describe.

As part of the OpenSSF badge to cover dynamic code checking, testing binaries is an accepted building block to solve this. checksec checks for properties of executables (like PIE, RELRO, Canaries, ASLR, Fortify Source) and can provide JSON output for automated processing.

https://slimm609.github.io/checksec.sh/

Describe the solution you'd like

Running checksec as part of the pipeline during Pull Requests and assert that fortifications are present.

./checksec --extended --file=controller

(--format=json provides json output)

Describe alternatives you've considered

Running as a job that is allowed to fail is another option. This seems unlikely to happen once it is working but not impossible e.g. when a new feature is added. One solution may be version pinning though.

Environment

• Production builds

Additional context

• generally the whole problem space gets simpler for fully static binaries, however cgo is by default enabled for DNS resolution to make use of nsswitch.conf https://pkg.go.dev/net#pkg-overview (and openssl when using the Microsoft fork)
