Deactivate a test which takes too long with BDDs

One of the JBMC tests will take a long time when BDD are used.
We deactivate it for now in the case BDD_GUARDS is defined.
This is acceptable since using BDDs for guards is still experimental.
Ideally we should find what takes too long in the execution and optimize
it, but it may be that we hit a particular class of guards for which the
BDDs have to be big.

+This test is deactivated for the build with BDDs because it takes more

+This is due to the size of the BDD representing the guards growing more than
