signal: Move sys_siglist to a compat symbol
The symbol was deprecated by strsignal and its usage imposes issues such as copy relocations. Its internal name is changed to __sys_siglist and __sys_sigabbrev to avoid static linking usage. The compat code is also refactored, since both Linux and Hurd usage the same strategy: export the same array with different object sizes. The libSegfault change avoids calling strsignal on the SIGFAULT signal handler (the current usage is already sketchy, adding a call that potentially issue locale internal function is even sketchier). Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi on all affected platforms. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
