build: address util.log.logcrash package rename

After `util.log` was renamed to `util.log.logcrash`, the build system
stopped updating the Sentry environment variable properly. Instead of
setting it to the release version, it was falling back to the default
"development" value. As a result, all Sentry reports went to the
development environment bucket.

This patch addresses the name change.

Release note: None

Release justification: fixes Sentry-to-GitHub crash reporting
