Subject: [PATCH v2 0/2] Fix Coverity builds on Windows

As of three weeks ago, Git for Windows' Coverity builds fail
[https://github.com/git-for-windows/git/actions/workflows/coverity.yml?query=branch%3Amain].

The reason is most likely the most recent Coverity release, 2025.3. Its
release notes
[https://documentation.blackduck.com/bundle/coverity-docs/page/webhelp-files/relnotes_latest.html]
do not shed any light into the issue (and do not mention that they bundle
JDK20 and JDK22 in addition to a JRE, because what's better than a single
Java installation: three, right?).

My investigation turned up .dll files that are located in Coverity's bin/
directory which have the same name as .dll files in Git for Windows' SDK. As
a consequence, the former override the latter and throw off MSYS2's logic to
find the MSYS2 root directory given the location of certain .dll files.

This patch series fixes this issue, and while at it, enhances the Coverity
workflow to print out the build log in case of failure. It is a companion of
https://github.com/git-for-windows/git/pull/5672 and of
(https://github.com/microsoft/git/pull/764.

Changes since v1:

 * Dropped unnecessary, non-portably cygpath call.
