oslib-posix: Align to permit transparent hugepages on ARM Linux

Browse Source 
ARM Linux (like x86-64 Linux) can use transparent hugepages for
KVM if memory blocks are 2MiB aligned; set QEMU_VMALLOC_ALIGN
accordingly.

/* 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. */
