Jota bfbd5e7a05 fix(libc): let a raised fault signal end the process under the macOS write watch ...

The macOS write watch handles SIGBUS and SIGSEGV for the whole process.
When a signal is not a write to a watched page and no handler was
installed before it, the handler restored the default action and
returned. That ends the process for a real fault, which runs again and
faults with the default action, but a SIGBUS or SIGSEGV sent with raise
or kill was swallowed: the process kept running. A spawned child that
raised SIGBUS exited with its next exit code instead of dying with the
signal, so guest_posix_spawn failed on macOS.

The handler now raises the signal again after restoring the default
action. It is blocked until the handler returns, so a real fault still
ends with the same signal, and a sent one now does too. An inherited
SIG_IGN keeps the old behaviour.
