selftests/bpf: Add bench for task storage creation

Browse source

This patch adds a task storage benchmark to the existing
local-storage-create benchmark.

For task storage,
./bench --storage-type task --batch-size 32:
   bpf_ma: Summary: creates   30.456 ± 0.507k/s ( 30.456k/prod), 6.08 kmallocs/create
no bpf_ma: Summary: creates   31.962 ± 0.486k/s ( 31.962k/prod), 6.13 kmallocs/create

./bench --storage-type task --batch-size 64:
   bpf_ma: Summary: creates   30.197 ± 1.476k/s ( 30.197k/prod), 6.08 kmallocs/create
no bpf_ma: Summary: creates   31.103 ± 0.297k/s ( 31.103k/prod), 6.13 kmallocs/create
