exec: Fix broken build for MinGW (regression)
Commit
3435f39513a104294b5e3bbf3612047028d25cfc reduced the ifdeffery with
this result for MinGW:
exec.c: In function ‘qemu_ram_free’:
exec.c:1239:17: warning:
implicit declaration of function ‘munmap’ [-Wimplicit-function-declaration]
exec.c:1239:17: warning:
nested extern declaration of ‘munmap’ [-Wnested-externs]
exec.c:1239: undefined reference to `munmap'
Add some ifdeffery again to fix this.
