Revert "Migrate hardcoded make to ${CMAKE_MAKE_PROGRAM}"

This reverts commit 085666b.

Even though the change in this commit is wanted, either RetDec
or Yara can't work with CMAKE_MAKE_PROGRAM when it is set to ninja
properly.

This commit is reverting the state to the previous working state
until it is fixed.
