Subject: [PATCH] use <sys/prctl.h> to enhance portability (clang)

using <sys/prctl.h> and <linux/prctl.h> simultaneously causes clang to
fail:

```
In file included from FEX/FEXCore/Source/Utils/AllocatorHooks.cpp:6:
/usr/include/sys/prctl.h:88:8: error: redefinition of 'prctl_mm_map'
   88 | struct prctl_mm_map {
      |        ^
/usr/include/linux/prctl.h:134:8: note: previous definition is here
  134 | struct prctl_mm_map {
      |        ^
1 error generated.
```

prefer <sys/prctl.h> and do not include <linux/prctl.h>

fix: #5454
