bind: use 0 instead of nil for the jclass zero value

Browse Source 
Go 1.10 was supposed to change the jclass JNI type to map to Go
uintptr, but failed to map the Android NDK definition until
recently.

There was a single instance in the reverse binding generator that
compared jclass values to nil. Change it to use 0 and cast the
jclass value to uintptr to ensure compatibility with older Go
releases.
