Update osslsigncode to more recent version

In projects/osslsigncode we are still using an old version of osslsigncode.

We have two patches, which I think can be dropped:

timestamping.patch which is used to allow timestamping with the add command. A similar patch was done upstream in https://github.com/mtrojnar/osslsigncode/commit/62e8ffd0c9aedf844452b80c5a72f3d0808cabbe
0001-Make-code-work-with-OpenSSL-1.1.patch which is adding support for OpenSSL 1.1 and is probably not needed with current version

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
