Move page_size_init earlier

The HOST_PAGE_ALIGN macros don't work until the page size variables
have been set up; later in postcopy I use those macros in the RAM
code, and it can be triggered using -object.

Fix this by initialising page_size_init() earlier - it's currently
initialised inside the accelerators, move it up into vl.c.
