perf test: Replace legacy `...` with $(...)
As detailed in https://www.shellcheck.net/wiki/SC2006:
The use of `...` is legacy syntax with several issues:
1. It has a series of undefined behaviors related to quoting in POSIX.
2. It imposes a custom escaping mode with surprising results.
3. It's exceptionally hard to nest.
$(...) command substitution has none of these problems,
and is therefore strongly encouraged.
