Signing (signcode-tf) failed on Windows 7 when SHA256 hash algorithm is used

[djpereira]

When I try to run build -w under Windows 7, the signcode-tf library fails as you can see below, when you try to sign using SHA256 only.

@develar this is similar to #581, however it fails with a different error with a single hash algorithm, if that algorithm happens to be SHA256. It works well with SHA1 under Windows 7 with both the Signtool.exe under the windows-6 folder and the one under the windows-10 folder.

electron-builder v5.12.1
target: Windows.
