P31XX & P51XX: fix Camera on Android 4.4.3 (HACK)

Hack by Unjustified Dev @ XDA

Issue where blob is loading libexif when it needs libjhead the old
libexif.

This hack is confirmed working for all the closed source. This hack
renames the string in camera blob that loads libexif to libhead.
libjhead won't fit too many characters.
