https://boringssl-review.googlesource.com/c/34188 accidentally disabled
it (__ARM_MAX_ARCH__ wasn't defined), which, in turn, masked a bug in
https://boringssl-review.googlesource.com/c/34874.
Remove the __ARM_MAX_ARCH__ check as that's hardcoded to 8 anyway. Then
revert the problematic part of the bsaes-armv7.pl change. That brings
back the somewhat questionable post-dispatch to pre-dispatch call, but I
hope to patch the fallbacks out soon anyway.
