Fixed few bugs #3

Bug 2:

on integrity.h,

        // fallback: first section with IMAGE_SCN_MEM_EXECUTE
        constexpr uint32_t IMAGE_SCN_MEM_EXECUTE = 0x20000000;
        for (uint16_t i = 0; i < nt->FileHeader.NumberOfSections; ++i) {
            if (section[i].Characteristics & IMAGE_SCN_MEM_EXECUTE) {
                text_va = reinterpret_cast<uintptr_t>(base) + section[i].VirtualAddress;
                text_size = section[i].VirtualSize;
                return true;
            }
        }
    } __except (1) {}

IMAGE_SCN_MEM_EXECUTE is a macro that is predefined in ntimage.h, if that header is imported somewhere else in project.
attempting to declare and initialize a constant with same name will make variable name expand to a constant value after preprocessing.

**Fix: ** i have wrapped it in an #ifndef IMAGE_SCN_MEM_EXECUTE block
