GetPrerequisites: Do not fail on files we cannot find
Historically we have always warned and skipped missing files. Since
commit v3.4.0-rc1~264^2~1 (GetPrerequisites: Add error checks for
execute_process() calls, 2015-07-29) we fail instead, but this was not
an intentional part of that change. Restore the warn-only behavior so
that missing system libraries (e.g. during cross-compiling) do not cause
failure.
Closes: #16523
