Brooks Davis c6e072f15c memfd_create: don't allocate heap memory 
Rather than calling calloc() to allocate space for a page size array to
pass to getpagesizes(), just follow the getpagesizes() implementation
and allocate MAXPAGESIZES elements on the stack.  This avoids the need
for the allocation.

While this does mean that a new libc is required to take advantage of a
new huge page size, that was already true due to getpagesizes() using a
static buffer of MAXPAGESIZES elements.
