Refactoring in 0036d1f7eb95bcc52977f15507f00dd07018e7e2 (v4.10) caused Linux to
start unconditionally zeroing the remainder of the last page in the
interpreter. Previously it did not due so if filesz == memsz, and *still* does
not do so when filesz == memsz for loading binaries, only interpreter.
This inconsistency is not worth replicating in gVisor, as it is arguably a bug,
but our tests must ensure we create interpreter ELFs compatible with this new
requirement.

Linux changed this behavior in 16e72e9b30986ee15f17fbb68189ca842c32af58
(v4.11). Previously, extra pages were always mapped RW. Now, those pages will
be executable if the segment specified PF_X. They still must be writeable.

* A segment with filesz == 0, memsz > 0 should be an anonymous only
mapping. We were failing to load such an ELF.
* Anonymous pages are always mapped RW, regardless of the segment
protections.
