base-hw: let upgrade_cap_slab reflect Out_of_caps
This patch reflects the Out_of_caps exception from core to the client, in addition to the already covered Out_of_ram exception. It thereby eliminates a potential abort in core, which I observed with the tool_chain_auto.run script: Kernel: RPC upgrade_cap_slab Error: Uncaught exception of type 'Genode::Quota_guard<Genode::Cap_quota>::Limit_exceeded' Warning: abort called - thread: entrypoint In addition to propagating the exception, the patch add the client-side exception-handling code to the base library. Fixes #3703
