selftests/bpf: Add bench for task storage creation
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
