Fix -linux-user build by reverting r5701

Unfortunately, -linux-user doesn't use osdep as it replaces some of those
functions with specific ones.  The code #ifdef code in exec.c needs to
remain in place so instead of introducing a qemu_getpagesize() let's just
use getpagesize() in the non-Windows implementation of qemu_vmalloc.
