fix(build): exclude *.log from ant package output

Ant <fileset> excludes are independent from .gitignore — files git
ignores are still picked up by the artifact target's recursive copy
unless explicitly excluded. bitbucket.log (gitignored, line 23) was
landing in the dist zip for that reason.

Adding **/*.log to the artifact fileset excludes. Confirmed no tracked
.log files exist anywhere in the repo, so this is purely additive.
