chore(ci): make the awslc fips install script version aware

[dougch]

Release Summary:

Resolved issues:

none

Description of changes:

AWS Libcrypto FIPS 3.0 needs to be part of our testing. This PR makes converts the 2022 installer into a symlink, with the underlying script choosing the feature branch based on the command name. This is an attempt at anticipating future versions of lc.

Call-outs:

The original awslc install script, which installs the 2021/v1 FIPS code, was not altered.

Testing:

How is this change tested (unit tests, fuzz tests, etc.)? locally

Remember:

• Any change to the library source code should at least include unit tests.
• Any change to the core stuffer or blob methods should include CBMC proofs.
• Any change to the CI or tests should:
  1. prove that the test succeeds for good input
  2. prove that the test fails for bad input (eg, a test for memory leaks fails when a memory leak is committed)
