put compat getpagesize into the right object list

Was getting this linker error building shared libraries on Windows:

Creating library C:/projects/portable/build/ssl/Release/ssl.lib and object C:/projects/portable/build/ssl/Release/ssl.exp
recallocarray.obj : error LNK2019: unresolved external symbol getpagesize referenced in function

getpagesize should be in compat rather than crypto object file list.
