src/borg/crypto/low_level.pyx: fix compiler warning 

The generated source code was producing a compiler warning due to
the pointers differing in constness. The called function expects
a non-const pointer while the generated code produces a const pointer
via a cast. This changes the cast to drop 'const' to make the compiler
happy.
