base-hw: let upgrade_cap_slab reflect Out_of_caps

Browse Source 
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
