linux-user: Remove qemu_host_page_size from create_elf_tables

linux-user: Remove qemu_host_page_size from create_elf_tables

AT_PAGESZ is supposed to advertise the guest page size.
The random adjustment made here using qemu_host_page_size
does not match anything else within linux-user.

The idea here is good, but should be done more systemically
via adjustment to TARGET_PAGE_SIZE.
