AOSP: Stop explicitly specifying -fno-strict-aliasing

AOSP: Stop explicitly specifying -fno-strict-aliasing

The upstream build system for e2fsprogs doesn't use
-fno-strict-aliasing, so update the Android.bp files to match.

Note: Android's build system currently uses -fno-strict-aliasing by
default anyway, so this change doesn't actually enable strict aliasing.
But that's a bit besides the point.  The point is that this project
doesn't need anything special, so we don't need to do anything special.
