rpm: fixed update error if working directory was removed

In this release, it was fixed update error if temporary working directory was removed.

In the previous versions, if temporary working directory was removed by tmpfiles.d, there was a case that updating to v6 (up to v6.0.1) causes fatal error while rpm processes transaction.

Now, with changing temporary working directory handling, it was fixed in v6.0.2.

msi: fixed installation rollback issue when executing maintenance script

Since v6.0.0, installation maintenance script (powershell) was partially introduced for Windows. But in some environments, there is a case that the execution of powershell was prohibited in your policy. In such a case, installation process will be failed unexpectedly.

In this release, added fallback not to terminate installation process accidentally.
