crimson/common: let's dump the core on fatal signal.

Removing the call to engine's `exit()` should allow the singnal
handler to exit. In the case of `SIGSEGV` this would return back
to the problematic instruction, and thus retrigger the fault.
As our handler already restores `SIG_DFL`, it's expected to get
a core dump.
