tests/vb2_firmware_tests: Improve workbuffer usage test

This patch changes vb2_firmware_tests to run multiple times with
different combinations of signature and hash algorithms. The goal is to
have more confidence that our recommended work buffer size is still big
enough even if we changed algorithm combinations in an RW update. It
also changes the underlying vb20_verify_fw to not just print the amount
of work buffer used at the end, but to detect the actual high water mark
of work buffer used during the test.

Also add some fallback definitions for undefined environment variables
to tests/common.sh which helps running individual test scripts without
the Makefile harness.
