GetPrerequisites: Recognize absolute paths to UCRT system libraries

The matching expression added by commit v3.5.0-rc1~33^2
(GetPrerequisites: Define api-ms-win-* files as system libraries,
2016-01-19) did not account for absolute paths to the UCRT libraries.
We already recognize absolute paths to the MSVC runtime libraries.
Do this for UCRT libraries too.

Issue: #16240
