Block syscall related to signal handling
https://bugs.webkit.org/show_bug.cgi?id=246020
<rdar://100604972>
Reviewed by Youenn Fablet.
The syscall SYS_sigreturn was unblocked in <https://commits.webkit.org/255036@main>, but it turns out
it is sufficient to block it without the default process termination behavior.
