SC2006: Use $(..) instead of legacy `..`.

Backtick command substitution `STATEMENT` is legacy syntax with several
issues.

 - It has a series of undefined behaviors related to quoting in POSIX.
 - It imposes a custom escaping mode with surprising results.
 - It's exceptionally hard to nest.

$(STATEMENT) command substitution has none of these problems, and is
therefore strongly encouraged.
