Streamline building and running all tool chains

[KinanBab]

Lints:

• Test existing lints, make sure they cover all traits
• Update workspace dylint and README to refer to git version of alohomora_lints
• Run lints as part of build.rs

PCR Signing:

• Test existing signatures, many will fail due to recent changes, resign them
• Simplify signing by making it into a cargo command
• Validate signatures in build.rs

Scrutinizer:

• Update scrutils dependency in alohomora_lints to use github rather than a local path
• Install scrutinizer as a build dependency of some sort from github instead of relying on it being pre-installed (alohomora_build)
• Test scrutinizer again on remaining applications: confirmed to work fine on Voltron
• Scrutinizer cannot run properly within build.rs currently, requires a cargo clean and manual run to work, consider pointing it to a different target dir to avoid current corruptions and allow it to run in build.rs

Sandbox:

• Reasonable currently, but will require manual building/copying of .so when several layers of dependencies. See Makefile for protfolio and websubmit harnesses. Fix this in a more consistent way.
