gh-36837: update qepcad to B 1.74
    
As noted in #36835, we missed an update to qepcad done in 2021. It has
made it into Debian and Fedora,
and we use Debian's tarball and patches (most of the latter are updated
versions of our B 1.72 patches)

We removed 'B' from the version number to accommodate the tarfile name
from Debian.

We also update saclib to the latest version

Fixes #36831
Fixes #36835
    
URL: #36837
