Harden build options suggested by rpminsect

• See: https://artifacts.dev.testing-farm.io/ac84345b-5cad-43b4-bede-91aa3137fdf5/
• Leaving -O2 and -g to default compilation default, as suggested by meson.
• Not sure if this works because I don't yet know how to run rpminspect locally on our compiled package.
