[PATCH i-g-t v14 02/11] tests/intel/*_intel_bb: handle base64 encode fail

[Jeevaka Prabu Badrappan]

g_base64_encode function returns a newly allocated string containing
the Base64 encoded data. Failure case is not handled.

When g_base64_encode function fails, set the outsize to 0 to address
null pointer dereference crash.
