[PATCH 5/7] rteval: Display core sharing warnings in text report

[John Kacur <jkacur@redhat.com>]

Add XSLT template to display CoreSharingWarnings in the text report
generated with the -Z option. The warnings appear after the "Tuned state"
section and before "System load" in the report output.

The template conditionally displays the "Core Sharing Warnings:" section
only when warnings are present in the XML, keeping the report clean when
there are no core sharing issues detected.

Example output:
   Core Sharing Warnings:
       Warning: Housekeeping CPU 0 (isol) shares core with measurement CPU 8 (isol)
       Warning: Measurement CPU 1 (isol) shares core with load CPU 9 (isol)

This completes the core sharing validation feature by making the warnings
visible in both the XML report and the human-readable text summary.
