libnativeheader exports headers under nativeheader. These were
available before incorrectly as global headers in order to give
access to jni.h.
Test: modules using system/core find headers

The compiler will issue the unaligned access instuctions
when reading from a packed struct. Since 'find' takes a
reference, if we pass the field directly it is removed
from its packed context and may be unreadable.
Read the field out directly from the packed struct and pass
in aligned to u_map to fix.
