feat(build): Update dependencies (#1847)

Remove dependencies which are already installed via other dependencies:
- eslint (gulp-eslint)
- istanbul (gulp-eslint)
- mocha (gulp-mocha)

Remove unused dependency:
- gulp-util

Move installing `lcov-result-merger` to Travis config since it's the only place where it's ever used.

Update a bunch of outdated dependencies.
