Remove RIDS in CompareMsftToSbAssemblyVersions test

[ellahathaway]

Closes dotnet/source-build#4493

When testing the changes in #41929, the CompareMsftToSbAssemblyVersions was continuing to fail with the following error message:

Unable to find matching file for 'packs/runtime.centos.9-x64.Microsoft.DotNet.ILCompiler/x.y.z/sdk/System.Private.StackTraceMetadata.dll' in '/tmp/t3vand3s.y0t/msft'

This file should fall under the following exclusion that exists in the exclusions file: ./packs/runtime.banana-rid.Microsoft.DotNet.ILCompiler/|sb. Upon investigation, I discovered that the issue was that unlike the CompareMsftToSbFileList test, the CompareMsftToSbAssemblyVersions test does not remove the RID from the file.

The fix here was to 1) Remove the RID from the SB file, and 2) replace the placeholder rids with matching patterns when attempting to file match to the Msft SDK.

• Failing test without changes (internal Microsoft link)
• Successful test with changes (internal Microsoft link)

We should merge this before merging in #41929

@dotnet/source-build-internal - the failures are unrelated to these changes. Can someone please bypass the checks for this PR? These changes are necessary for a green SDK diff pipeline run. TIA
