Fix header and library capitalization for cross compilation

[nhz2]

I am working on updating the Julia programming language to the latest version of 7zip Ref: JuliaPackaging/Yggdrasil#12372
We use cross-compilation to build 7zip for all supported platforms on a Linux machine.

I had to adjust the capitalization of a header file and some -l flags to get the cross-compilation to work.

I'll fix it so:

#if defined(__MINGW32__) || defined(__MINGW64__)
#include <ntsecapi.h>
#else
#include <NTSecAPI.h>
#endif

We need these checks for mingw, because some another compilers still expect <NTSecAPI.h>.
