enable CONFIG_FPROBE

Certain ebpf related networking tools like pwru require this to be true. There should be close to no impact from enabling it

How to use

  • Validate config set in built image grep CONFIG_FPROBE /boot/config-$(uname -r)
  • Optionally, validate by running pwru with the kprobe-multi backend and confirming that it starts successfully.

Testing done

[Describe the testing you have done before submitting this PR. Please include both the commands you issued as well as the output you got.]

  • Changelog entries added in the respective changelog/ directory (user-facing change, bug fix, security fix, update)
  • Inspected CI output for image differences: /boot and /usr size, packages, list files for any missing binaries, kernel modules, config files, kernel modules, etc.
