test.bash: add staticcheck to our integration tests

This adds the use of the staticcheck tool to check our code.
The use of staticcheck would have caught a bug in CL/211737.
Also, we adjust one minor code patterns to avoid triggering
one of the staticcheck checks.

This CL also modifies the integration script to check SHA256
checksums for archives downloaded from a third-party source.
