Lagom: Work around gcc codegen bug

Browse Source 
Without this, GenerateUnicodeData crashes when run during the build.
With this, `serenity.sh run` brings up a running SerenityOS.
Since GenerateUnicodeData doesn't take a lot of time to run, just
disable optimizations to work around the problem for now.

Works around #15449.
