GruzzberryandClaude Sonnet 5.5 1fbf3a42d2 fix(libkernel): fail the signal action, mask, stack and pending calls with EFAULT on an unusable pointer ...

FreeBSD 11.4's sys_sigaction, sys_sigprocmask and sys_sigaltstack copy
their input in before validating it and copy the old value out after
the change, and sys_sigpending copies out; a bad pointer gives EFAULT.
The guest pointers were dereferenced directly.
