cyrus-sasl: patch packaged headers to work with msvc compiler

[adamws]

Specify library name and version: cyrus-sasl/2.1.28

When using msvc compiler and saslplug.h include, it would fail to compile test_package.
I addressed that problem here: cyrusimap/cyrus-sasl#831 - until solved upstream I think this qualifies for patching here (which this PR does)

Thanks a lot! We really appreciate you opening the issue upstream and linking back there in the code <3

My understanding is that upstream will fix this similarly to how you've implemented here, but let's give them a few days just in case they supprise us, else I'll aprove by monday :)
