Update workflows

Update the GitHub actions workflows using a subset of the changes
from the master branch, commit 620a977f22.  Cherry-picking each
relevant commit would have resulted in a large number of conflicts
so this change only applies a minimal set of useful updates.

- Added build-dependencies.txt and checkstyle-dependencies.txt
- Added reclaim_disk_space.sh script
- Minor changes to build steps
- Reduced ztest run time
- checkbashisms, mandoc, and cppcheck were not included to
  avoid additional backports
- Add exceptions for shellcheck
