Subject: Add syscall count benchmark for 002_hello.ts (#820)

* Add syscall count tracking for benchmark

* Add fetch_deps thread benchmark

* Switch to `strace -c` for syscall parsing

* Spawn http_server during benchmark (for fetch)

* Rename `benchmarks` to `exec_time_benchmarks`

* Update app_test.js
