build: compiles build scripts with optimization (#175)

Without this running `lalrpop` runs for a long time unoptimized.  This
trades off some build time to make the grammar generation much cheaper
and makes the build 50% faster on my workstation.

Also fixes a minor typo in `partiql-parser/build.rs`.
