Update UPX version from 3.91 (Sept 2013) to 3.95 (Aug 2018)

[CockRobbin]

Hello team,

The UPX version embedded in WSUSOffline
and used to compress the AutoIt compiled executables,
is largely outdated.
Current UPX.exe has version 3.91 (Sept 2013)
The new available version is 3.95 (Aug 2018),
and is available from the author's Web site:
https://upx.github.io/

Thanks!
Best regards,
Cock Robbin.

The WSUS Offline exectuables have not been compressed anymore for a quite a while (version 11.3 to be exact)), neither with UPX nor with AutoIT's own compression method. So, no need to update UPX IMO.
