Deprecated dependency in tidy's `deps.rs`

[pierwill]

According to crates.io, cpuid-bool is deprecated. However, it is listed in the permitted dependencies:

rust/src/tools/tidy/src/deps.rs

Line 96 in 498eeb7

"cpuid-bool",

cpuid-bool is being pulled in by two hashing crates:

rust/Cargo.lock

Lines 4713 to 4737 in 4c55c83

	"cfg-if 0.1.10",
	"cpuid-bool",
	"digest 0.9.0",
	"opaque-debug 0.3.0",
	]

Both of these crates now use cpufeatures.

We should update sha2 and sha-1 to use the currently maintained crate.
