Subject: [PATCH v4 01/20] perf bpf-prologue: Remove unused file

Commit 4a73fca22692 ("perf bpf-prologue: Remove unused file") missed
cleaning up the header file. The code was unnecessary as Commit
3d6dfae88917 ("perf parse-events: Remove BPF event support") removed
building bpf-prologue.c.

Fixes: 4a73fca22692 ("perf bpf-prologue: Remove unused file")
