linux-user: fix tcg/mmap test 

tests/tcg/mmap test fails with values other than default target page
size. When creating a map beyond EOF, extra anonymous pages are added up
to the target page boundary. Currently, this operation is performed only
when qemu_real_host_page_size < TARGET_PAGE_SIZE, but it should be
performed if the configured page size (qemu -p) is larger than
qemu_real_host_page_size too.
