From: Johannes Schindelin <johannes.schindelin@xxxxxx>
When I added the Coverity workflow in a56b6230d0b1 (ci: add a GitHub
workflow to submit Coverity scans, 2023-09-25), I merely converted an
Azure Pipeline definition that had been running successfully for ages.
In the meantime, the current Coverity documentation describes a very
different way to install the analysis tool, recommending to add the
`bin/` directory to the _end_ of `PATH` (when originally, IIRC, it was
recommended to add it to the _beginning_ of the `PATH`).
This is crucial! The reason is that the current incarnation of the
Windows variant of Coverity's analysis tools come with a _lot_ of DLL
files in their `bin/` directory, some of them interferring rather badly
with the `gcc.exe` in Git for Windows' SDK that we use to run the
Coverity build. The symptom is a cryptic error message:
make: *** [Makefile:2960: headless-git.o] Error 1
make: *** Waiting for unfinished jobs....
D:\git-sdk-64-minimal\mingw64\bin\windres.exe: preprocessing failed.
make: *** [Makefile:2679: git.res] Error 1
make: *** [Makefile:2893: git.o] Error 1
make: *** [Makefile:2893: builtin/add.o] Error 1

Warning: Build command make.exe exited with code 2. Please verify that the build completed successfully.
Warning: Emitted 0 C/C++ compilation units (0%) successfully

For more details, please look at:
D:/a/git/git/cov-int/build-log.txt
The log (which the workflow is currently not configured to reveal) then
points out that the `windows.h` header cannot be found, which is _still_
not very helpful. The underlying root cause is that the `gcc.exe` in Git
for Windows' SDK determines the location of the header files via the
location of certain DLL files, and finding the "wrong" ones first on the
`PATH` misleads that logic.
Let's fix this problem by following Coverity's current recommendation
and append the `bin/` directory in which `cov-int` can be found to the
_end_ of `PATH`.
