Subject: [PATCH] CMake: Fix regular expression for BLAKE2 SSE2 source files
 selection

The comparison was being made against the variable's name instead of its value, causing the result to always be true.
For reference: https://cmake.org/cmake/help/v3.10/manual/cmake-generator-expressions.7.html#genex:BOOL

In addition to that, this commit also fixes the source file name of the non-SSE2 code.
