EGLAttrib requires special handling in JNI

EGLAttrib is defined for a C / C++ interface and is
intended to be the size of a pointer. That can change
depending on which abi the code is built for but Java doesn't
have a way of dealing with such types. Java defines EGLAttrib
as a jlong, so need to convert jlong to 32bit when running on
a 32bit device.
