Subject: [PATCH bpf-next v2 7/7] tools: bpftool: complete metrics list in "bpftool prog profile" doc

Profiling programs with bpftool was extended some time ago to support
two new metrics, namely itlb_misses and dtlb_misses (misses for the
instruction/data translation lookaside buffer). Update the manual page
and bash completion accordingly.

Fixes: 450d060e8f75 ("bpftool: Add {i,d}tlb_misses support for bpftool profile")
