Support new interpreter requirements in test
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. PiperOrigin-RevId: 272266401
