insane.bbclass: Fix ELF bitsize comparison
Fix the way the ELF size is compared to ensure that incorrectly sized ELF binaries are captured during the file scan. lib/oe/qa.py is changed to accept a bitsize as a parameter. Instead of previously defining true/false, it now takes "0" undefined, "32" 32-bit, and "64" 64-bit as the size argument. This allows us to preserve existing behavior of only loading one ELF type, while allowing the function to be able to discover the size on it's own.
