chore: remove unused files and code

- Delete obsolete RPM maintainer scripts (postinst, prerm, postrm)
  Scripts are now embedded in ja4sentinel.spec
- Delete unused RPM test script (test-rpm.sh)
  Referenced non-existent el7 builds, not integrated in CI
- Remove unused constants and functions from api/types.go:
  - DefaultInterface, DefaultPort, DefaultBPFFilter
  - DefaultFlowTimeout, DefaultPacketBuffer
  - LogLevelDebug, LogLevelInfo, LogLevelWarn, LogLevelError
  - DefaultConfig() function
- Update Makefile with RPM_DIR variable for consistency
