Benchmarking The Performance Overhead To The Linux Kernel Runtime Guard

Besides code compilation and SQLite, another real-world area affected was the Inkscape vector graphics program when dealing with lots of file activity.

While a micro-benchmark, the test case having the worst hit from LKRG being active was Stress-NG's forking benchmark.

Fortunately, most other workloads tested saw minimal to no performance hit from the Linux Kernel Runtime Guard.
