stagefright aacenc/amrwbenc: Remove trailing whitespace

This was applied in AOSP master earlier, in commit
b21611e, but when merged
into the Google internal tree in
88c2d4d, none of these
changes have been brought in. (The diff of this merge commit
and its first parent, d94b71d, is empty.)

Therefore, reapply the rest of these changes on the files
that still are present in the current version.
