oslib-posix: Align to permit transparent hugepages on ARM Linuxkvm-arm-v14
ARM Linux (like x86-64 Linux) can use transparent hugepages for KVM if memory blocks are 2MiB aligned; set QEMU_VMALLOC_ALIGN accordingly. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

/* Use 2 MiB alignment so transparent hugepages can be used by KVM.
Valgrind does not support alignments larger than 1 MiB,
therefore we need special code which handles running on Valgrind. */
